Today, Motorola (MOT) is unveiling its $100 Motopure H15 Universal Bluetooth Headset. It’s available from Verizon’s (VZ) stores and Web site, and I’ve been testing it.

While focusing on the new Motopure H15, I also took another look at two noise-canceling headsets we reviewed in May — the $130 Jawbone from Aliph Inc. and the $120 Plantronics (PLT) Discovery 925. I made calls on the three headsets while standing beside a construction crew’s loud generator in busy downtown Washington, D.C., and, in a separate test, running my hairdryer on high in the background.

In both of these loud scenarios, the results favored the Motopure over the Jawbone and Plantronics Discovery. Of the three, the Plantronics headset allowed the most background noise through and made it difficult for people to hear my voice. The Jawbone was much better than the Plantronics headset, but not as good as the Motopure, which dimmed loud background noise to a faint hum and seemed to amp up the volume of my own voice. I called various people and even left myself voicemails so I could hear the differences.

More Microphones

The Motopure H15 uses two microphones, while the Jawbone uses two microphones and one modified microphone that works as a voice-activity sensor. The Plantronics headset uses one microphone. Motorola says one of its microphones hears the user’s voice, the other picks up background noise and a technology called CrystalTalk works to filter that noise out.

In my Motopure testing, I saw at work technology that Motorola says is meant to automatically adjust the headset volume as noises increase or decrease in the background. And at no point during my tests with the headset did friends on the other end of the line notice any odd echoing or fading volume in my voice, as with some headsets.

Snug Fit

Unlike the Jawbone, which — as its name reflects — works by touching bones in the face to eliminate excess noise, the Motopure H15 never touches one’s face. In fact, Motorola cites this as an advantage over the Jawbone because it doesn’t need to touch a user’s face to work. Motorola’s headset fits using a loop of clear plastic that wraps snuggly around the ear, along with an in-ear piece, though it took me a little while to figure out which of its five earbuds fit best.

And unlike the Plantronics headset, which has a larger, triangular-shaped boom, the Motopure has a tiny boom that folds away when not in use. Users receive calls by simply folding the boom down, which instantly turns the headset on and connects to calls. When the boom is closed, the headset turns off to save battery. I liked the finality of closing the boom and knowing my headset was definitely off whenever I put it in my purse. And in its tucked-in position, the Motopure H15 is petite and portable.

But if you’re wearing this headset on your ear, opening and closing the boom is almost impossible. Motorola recommends using the boom as you would a clamshell cellphone: Answer calls by opening the boom before donning the earpiece and end calls by removing the earpiece and closing the boom.

Of course, many users will want to keep the device in their ear for an extended period, rather than fishing for it when a call comes in. For them, the awkwardness of the boom switch may be a problem. They can still keep the Motopure on with the boom opened, receiving and ending calls at any time by simply pressing the large Call button. In this state, the handset is in standby mode rather than off — the same as most Bluetooth headsets waiting for calls.

One Headset, Two Phones

A plus of the Motopure is its ability to simultaneously pair with two phones, such as a personal cellphone and a work smartphone. Incoming calls to both lines are represented by different colored lights on the headset. But as soon as a call with one phone begins, the Bluetooth link to the second phone is disconnected.

The Plantronics headset also has dual-phone pairing capability, but the Jawbone doesn’t.

According to Motorola, the Motopure’s battery lasts for about 4.5 hours of talk time. The Jawbone’s battery lasts four hours; the Plantronics headset, five hours. In standby, Motopure and the Plantronics Discovery last for about seven days; Jawbone lasts for eight. Pressing and holding the Motopure’s up and down volume buttons spurs an indicator light to glow red, yellow or green to represent battery strength.

I liked the Motopure’s sturdy charging stand, which doubles as a holder for the headset. Though this desktop charger isn’t available today from Verizon, it will be available later this month from other carriers and retailers in a $130 bundle with the headset.

More Colors Later

Today, the Motopure is available in a slate color, but it will be available in black later this month and other colors are tentatively planned for November. The Jawbone and the Plantronics headset are each available in three colors, and Jawbone will release blue and pink headsets later this month.

Overall, the Motopure H15’s noise cancellation worked the best out of these three headsets, and its tiny build and fold-up boom make it a helpful tool for consumers who want quiet conversations no matter where they are.

It seems that this last attribute — the ability to make and receive calls on a cellphone — is overlooked and underestimated by many manufacturers. But believe it or not, there are plenty of people out there who simply want to use their cellphones for calls, period.

These individuals range from college students who frequently damage or lose their phones to wary, first-time buyers to senior citizens whose kids or grandchildren insist they use a cellphone. About a year ago, GreatCall Inc. introduced its Jitterbug cellphones, which were aimed squarely at the senior set with large keys, a free operator service and the phone’s own number prominently displayed on a sticker.

It seems that GreatCall was on to something. Verizon Wireless recently followed the company’s lead by introducing its straightforward, no frills Coupe, a cellphone that offers many of the helpful traits found on Jitterbug phones, like large screen fonts, but without a lot of extras. Verizon simultaneously unveiled two calling plans designed specifically for seniors, and was followed a month later by AT&T and its own monthly plan for those 65 and over. AT&T also has an uncomplicated phone of its own in the works for 2008.

This week I tested Verizon’s $40 (with a two-year contract) Coupe (www.verizonwireless.com) against GreatCall’s $147 Jitterbug Dial (www.jitterbug.com) to see how the two stacked up. I found the Jitterbug more comfortable to use for longer phone calls because of its cushiony earpiece, which blocks out external sound and helps the phone rest easier between your shoulder and ear during conversations. And Jitterbug’s mantra of simplicity will appeal to cellphone newcomers.

But for those who have been using cellphones and are familiar with the way they work, Jitterbug’s nonconformist features — like Yes and No buttons in place of Send and End and the use of a dial tone whenever the clamshell-shaped phone is opened — can come across as too basic, to the point that they’re confusing. One example: many standard cellphones redial the last number called when the Send button is pressed twice, but redialing on the Jitterbug requires navigating through five screens to redial the last number.

The Coupe is the smaller of the two and blends in with other cellphones. It includes a few of the extra functions found in normal mobile phones, like an alarm clock, calculator and the capability to send and receive text messages; perhaps most people who buy the Coupe won’t use it for texting, but it’s nice to have the built-in option. (The Jitterbug doesn’t have any of these features.) Right now, this cellphone only comes in shiny black with a blue border around its outside display screen. An included charging cradle adds a touch of convenience.

The Coupe also has some fun features that give it a more personal touch, including a choice of 24 ringtones and 10 wallpaper designs for the main screen’s background. After seeing low-grade camera lenses on nearly every digital device that I’ve picked up recently, the Coupe looked a little naked without one.

Three red buttons labeled I, C and E (for In Case of Emergency) are positioned just below the phone’s screen and can be assigned names and numbers to work as shortcuts to those most often called. A specially marked “911″ button on the phone’s keypad is designated specifically for emergencies, though this must be held down to use and, even then, asks if the caller definitely intended to call 911.

A speaker button is also clearly labeled on the Coupe’s keypad, and pronounced volume adjustment keys line the phone’s side. On-screen fonts appear larger than those found on regular cellphones.

Verizon’s well-known network is sure to be a draw for potential buyers, especially because any plan used with the Coupe includes free calls to other Verizon Wireless users. Though any of this carrier’s plans work with this basic phone, the Nationwide 65 Plus plan made its debut with the Coupe in hopes of appealing to those ages 65 and up. A single-line plan allows 200 anytime minutes and 500 night and weekend minutes for $30 monthly; the two-line plan offers roughly double the minutes (to be shared) for double the price. These plans aren’t exclusively usable with the Coupe.

GreatCall’s Jitterbug comes in two $147 models: the Dial, with a numeric keypad and the OneTouch, with just three large buttons labeled Operator, Tow and 911. I’ve tested both in the past, but this time around I looked at the Dial because it’s most comparable to Verizon’s Coupe.

The Jitterbug Dial phone comes in black or white, and its buttons and all of its on-screen lettering appear considerably larger than the Verizon Coupe’s. Its number keys glow bright white and are encircled by yellow borders, while the Coupe’s digital keypad is black with glowing blue numbers — colors that aren’t as distinctive. Unlike the Coupe, Jitterbug doesn’t come with a charging cradle, though GreatCall has plans for adding cradles in 2008.

A free operator service can be reached from Jitterbug phones by pressing “0.” This operator greets users by name, places calls on the user’s phone (saving you the trouble of dialing) and can add numbers to a phone’s contact list if a user doesn’t want to or can’t do this.

The Jitterbug can be pre-programmed with names and numbers; I ordered mine with five pre-programmed numbers, a luxury that nervous new cellphone owners might find worthwhile. Things get difficult when you try to enter your contacts. Even though each number key has three or four letters assigned to its key as on all phones, adding a contact involves using Jitterbug’s clumsy system of choosing one letter at a time from the screen. You’re better off using the free operator service for this.

Jitterbug phones let users store only 50 contact names and numbers, while Verizon’s Coupe will store 500. Many first-time cellphone owners will be content with 50, but, again, options are good.

The Jitterbug and Coupe each have small screens on their outer shells that display the time, date and phone numbers of incoming calls. But the Coupe displays its remaining battery power both on this outer screen and inside on its main screen, while the Jitterbug only flashes battery status on the screen if the battery reaches a certain low level, or if you navigate to a special “Phone Info” screen.

Behind the scenes, GreatCall’s Jitterbug phones run using networks set up by other carriers; I never had any trouble dialing out or receiving calls. A variety of calling plans can be used with Jitterbug phones ranging from $10 monthly for pay-as-you-go at 35 cents a minute to $80 monthly for 800 minutes. Add-on packages of minutes and sharing plans are also available.

If you’re familiar with cellphones, the Jitterbug will be a confusing step back for you, even though its free operator service and comfortable earpiece are pluses. Some people will prefer the Jitterbug’s larger fonts and number keys to the Verizon Coupe’s smaller, more stylish build. Still, the Coupe is a good option for people who have at least some familiarity with technology and cellphones. Each in its own way does a good job of sticking to the basic task of handling phone calls.

VTech Communications wants to put an end to this mad phone dash with its new $150 Expandable Cordless Phone System with Bluetooth, the LS5145. This device synchronizes with your cellphone and redirects incoming cell calls to ring wherever the VTech phones are placed in the house. It works with your landline and up to two Bluetooth-linked cellphones, and can be expanded using additional handsets that cost $80 each.

The $150 Expandable Cordless Phone System with Bluetooth from VTech Communications Inc.

The concept of a cellphone extender isn’t new, but not many of them have caught on. Another popular add-on to cellphones at home is the repeater, which focuses on boosting a phone’s signal in a place with poor coverage. The VTech 5145 could work as a repeater, assuming you put it and the finicky cellphone in a place with good coverage. But if your entire house has lousy cell coverage, it won’t work as a repeater.

AT&T licenses its corded and cordless phones through VTech, which sells a less-expensive product similar to the 5145 called the AT&T EP5632. It costs $100 and has the same basic functions as the 5145, but is clunky and much less stylish. Its additional handhelds cost $60 each.

This week, I put my feet up and tried the VTech 5145 and one of its accessory handsets, the LS5105. These phones are stylishly thin and have bright color display screens, which can be set to one of 27 still color wallpaper images or four animated designs. It took me only a minute to pair cellphones with the system using Bluetooth, a wireless technology that connects devices that are within about 30 feet of one another. And the VTech’s primary function — extending the cellphone throughout a house to make it more convenient to answer — worked well, ringing much louder than my cellphone.

But the 5145 didn’t display the numerous names and numbers stored on my cellphone’s contact list. Unless I wanted to painstakingly enter the data into the VTech, incoming calls were only identified with phone numbers, so I rarely knew who was calling. And I could only call the handful of numbers that I know by heart.

Bluetooth technology isn’t incapable of transmitting data: My BlackBerry Curve even tried to transfer its contacts to the 5145, but couldn’t. VTech chose to use headset Bluetooth synchronization on the 5145 rather than hands-free synchronization. Hands-free is the same technology used in most Bluetooth-equipped cars; it provides more access to the Bluetooth device, such as phone-book integration.

I also missed other features on my cellphone when it wasn’t by my side, such as text messaging and voice mail. Incoming text messages were sent to my cellphone unbeknownst to me since I wasn’t near it, and when I didn’t answer incoming calls through the VTech, I had no way of knowing if the caller left a voice mail on my cellphone.

The 5145 includes a base station and primary phone; the 5105 additional handset includes a small stand just big enough to hold it upright. I set up the base station near where I drop my work bag after coming home each night. After the initial pairing during setup, phones automatically link to the VTech, meaning I never had to take my cellphone out of my bag.

I paired the 5145 with two phones at once: a Motorola Razr using Verizon and a BlackBerry Curve with AT&T service. I also tested pairing a third phone with the system, the HTC Pocket PC 6800 from Sprint, though only two cellphones can be paired simultaneously. Just one of the Bluetooth phones can be used at a time, in addition to the landline. As long as the two paired phones stayed within about 30 feet of the base station, they automatically started routing calls through the VTech.

Call waiting worked like using my actual cellphone, except I pressed different buttons on the 5145 to “swap” calls. If you’re chatting on a landline call, you can answer an incoming cellphone call by placing the landline call on hold. If each line — landline and cellular — has call waiting, a total of four callers could potentially be linked to the VTech system at once.

In my house, we gave up our landline years ago, so I tested the system using only cellphones. I saved myself a few trips racing up and down the stairs to find where I had left my cellphone, instead placing the base station on one floor and the additional handset on the other. Using cordless phones for the first time in years reminded me of the issues that accompany this system. The line became fuzzy when I moved too far away from a phone’s base station, though VTech says a connection can stay clear for up to about 900 feet.

I almost forgot that cordless phones can’t be taken out of the house. While on a phone call, I had to stop myself from heading out the front door and continuing my chat as I walked to the corner store. Cellular calls that are in progress on VTech handsets can be continued on the cell by adjusting a setting on the cellphone, or by walking far enough away from the base station to receive a cellphone prompt to disconnect from the system.

I made calls from the handsets by first choosing which of the paired cellphones to use. My calls were received by friends and family just as if I was calling on my cellphone, though a couple of people told me that the connection didn’t sound quite as good.

Each handset is equipped with a speakerphone, and missed calls are noted on the color screen and in a call log, along with the date and time. A built-in intercom system lets handsets communicate with the other or the base station. Users can choose from one of 23 ringtone-like melodies; I chose a steel drum tune for one handset.

If you’re looking for an easier way to answer your cellphone whenever and wherever it rings, VTech’s system might be a good solution for you. But if you rely on your cellphone’s address book to identify callers and aren’t up for inputting these data again, it might be worth waiting for a Bluetooth cordless phone system that will automatically copy data from your cellphone.

The Palm Centro

The two companies most often associated with corporate-issued devices, Research In Motion Ltd. and Palm Inc. are anxious to convert people like my friends. This week I tested Palm’s new attempt: the Centro (www.palm.com/centro). It looks like a hip, miniature version of the more expensive Palm Treo, with most of the same functions and only costs $99 after rebates and a two-year contract. The Centro comes in onyx and ruby, though the latter won’t be sold until next month.

Overall, I liked the Centro. It has plenty of pluses, including a touch screen, easy email set-up for personal accounts like Gmail and Hotmail, built-in instant messaging for three programs, a camera for still shots or video and expandable memory. It’s available now and runs on Sprint’s fast 3G network, costing at least $15 monthly for data on top of your voice plan. Like the Treo, it has a tiny stylus for detailed screen selecting and an on/off ringer switch.

RIM should be credited with introducing one of the first hip, mini smart phones to the demographic of 25-to-30-year-olds without smart phones. About a year ago, it brought out the $200 BlackBerry Pearl 8100, which is narrower than traditional BlackBerrys and is easy to mistake for a stylish cellphone. It uses a condensed keyboard with two letters per key that works using auto-correcting SureType technology, and has a glowing trackball for navigation.

For Palm’s Centro to compete with the Pearl, it, too, needed to be thinner left to right. But instead of doubling up letters per key and using SureType like the Pearl, the Centro has a shrunken version of Palm’s full keyboard; letter keys are squeezed so close together that large-fingered users will likely have trouble. I found the Pearl’s keyboard easier to use because its keys are flatter and larger compared with the Centro keys, which caused me to mistype messages. But the Centro’s tiny keyboard could be a real step up for people who still use their cellphone’s numbered keypad to type text messages.

The Centro’s touch screen saves time and makes navigation easier. The BlackBerry Pearl doesn’t have a touch screen, forcing users to do a lot of scrolling with the navigational trackball.

A success with the Centro would be much needed good news for Palm, which hasn’t had an easy go of it lately. While RIM has been cranking out more stylish BlackBerrys, Palm’s solid Treo hasn’t changed all that drastically in the past couple of years. Even loyal Treo users are starting to complain about Palm’s old operating system crashing. Of course, the popularity of Apple Inc.’s iPhone only rubs salt in the wounds of this once unstoppable company.

RIM will bring out a new Pearl, the 8130, next month to step up its game. This Pearl will be the same physically, but will have some internal changes, including the ability to work on the CDMA network, built-in GPS and upgraded software.

I tested a stylish ruby Centro and also got my hands on an early version of the BlackBerry Pearl 8130 from Verizon Wireless. Lined up side by side, the Palm Centro looks like a chubby version of the Pearl. The Pearl looks and feels sleeker and sharper than the Centro, due in part to the Centro’s rounded edges and tiny, bubble-shaped keys.

The Pearl is just a hair smaller in all directions — width, height and depth. The Centro is almost a full ounce heavier than the Pearl, but each weighs only 4.2 and 3.4 ounces, respectively. The Centro’s 320×320 resolution screen looks brighter than the Pearl’s 240×260 screen.

I focused on the Centro, setting up two personal email accounts on it in just a few minutes. I started out typing very slowly on the keyboard, which has keys made of a slightly sticky material. The more familiar I became with it, the faster I could go, but I’m still not completely comfortable using the keyboard.

I quickly navigated through the Centro’s menus using Palm’s familiar operating system. The touch screen saved me from arrowing around to select an icon or menu; I just tapped the screen using my finger or the stylus. First-time smart-phone users will appreciate this aspect.

I made calls on the Centro, pressing the phone shortcut key to get started. The keyboard’s number keys work just as they do on a Treo, but I preferred using the larger virtual buttons on the touch screen. The Centro felt like a normal cellphone in my hand and against my ear, especially compared with the clunky, rectangular Treos and BlackBerrys. The tiny Centro fit into the smallest purse I own.

An icon on the home screen marked “IM” linked me directly into a screen where I could log in to and use three instant-messaging programs simultaneously: AOL’s AIM, Yahoo Messenger and Windows Live Messenger. I jumped between IM sessions using the left and right navigation key buttons. But a faster way to do this was just by touching the screen to select a program. I also tapped the screen to select names of friends before IMing them. Again, the touch screen saved time and took out the guesswork of which key to press to navigate.

I played preloaded music on the Centro and BlackBerry Pearl; both have built-in speakers that sound remarkably good for such little devices.

Battery life on the Centro is estimated at 3.5 hours of talk time and up to 12.5 days of standby time. The Pearl 8130’s talk time is expected to fetch 3.8 hours before quitting, but its standby battery is expected to last only nine days. I didn’t perform rigorous battery tests, but found that my BlackBerry Pearl needed to be charged before my Palm Centro after a weekend of using them for roughly the same amount of time.

The BlackBerry Pearl 8130 comes with only RIM’s BlackBerry Messenger program. Both the Pearl and Centro have 64 megabytes of internal memory and the ability to expand that using microSD cards.

If you’re considering the leap from a cellphone to a smart phone but don’t want the bigger, geekier look of one of these helpful devices, the Palm Centro is a good option. Its keyboard will take some getting used to, but its touch screen will win you over by providing a simpler way to navigate — especially for smart-phone novices.

MobiTV, from MobiTV Inc., www.mobitv.com, gives people a way to watch television on their cellphones.

For lovers of portable video, the arguments in favor of TV on phones are speed and convenience. Rather than waiting to download movies, video podcasts and TV shows to a computer and then to transfer them to a portable player like an iPod, some would rather see current, live content streamed onto the device they already carry — their cellphone — whenever they want, wherever they are.

Live TV on cellphones isn’t new. We first tested it in 2004. But it was awful then, choppy and almost unviewable, because the cellular networks were too slow and the phones were too wimpy. So I decided to try it again.

Many cellphones are capable of displaying streamed television using built-in services, but few people are aware of these capabilities and not every phone will work as well as the next. The best results are delivered on devices with good quality screens that can retrieve and display the content using high-speed networks.

I used a mobile content-streaming service called MobiTV on three phones serviced by two carriers, Sprint Nextel Corp. and AT&T Inc.’s Cingular Wireless, watching a variety of shows on screens smaller than the palm of my hand. Monthly usage for watching cellphone TV with these two carriers costs about $25 and $30, respectively, on top of your voice plan. MobiTV is compatible with more than 150 handsets, offering roughly 40 channels — about half of which show live content like that found on your home TV.

All in all, MobiTV offers a fun and simple solution for people seeking TV on the run. High-quality images appeared on screen just moments after I opened the MobiTV application and an on-screen guide labeled each channel. TLC, ESPN, The Discovery Channel, The Oxygen Network and major news channels are entertaining enough. And though my eyes hurt after 30 minutes of watching such a small screen, I only ran into a few other snafus: on-screen images disappearing while audio continued, certain channels cutting out and lips moving out of sync with audio. In more cases than not, these instances were rare or corrected themselves in seconds.

Other carriers offer video clips that might easily be confused with MobiTV Inc.’s technology. Verizon Wireless, for example, offers its V Cast service. But V Cast requires that you download clips onto your device. Sprint and Cingular also offer video-on-demand options. But the MobiTV service streams content onto your phone, showing it just about a minute later than the same content on live TV.

If you don’t use Sprint or Cingular and you’d like to download MobiTV to your standard cellphone, or to your Palm or Windows Mobile smart phone, you can do so through third-party vendors like Handango.com; these options can be found on www.mobitv.com. Vendors charge about $10 a month on top of any data charges that you might owe your carrier.

MobiTV’s service includes a channel guide.

Sprint and Cingular encourage you to buy an unlimited monthly data plan in addition to your voice plan if you’ll be watching TV on your cellphone. Sprint calls its live-TV service Sprint TV Live — though it’s really MobiTV beneath the covers — and offers TV-inclusive data plans for $15, $20 or $25. These return 8, 13 and 25 channels respectively. Sprint’s exclusive content includes the NFL network. To further confuse matters, you can also buy stand-alone Sprint TV Live on top of those three data plans; it costs about $10 monthly. Cingular charges users about $20 for its unlimited data plan plus $10 for MobiTV usage. This carrier keeps the MobiTV name.

MobiTV worked relatively the same way on all three handsets with both carriers: two Windows Mobile devices, the Sprint PPC-6700 and Cingular 8525, and a basic cellphone, Samsung Electronics Co.’s SGH-A707 with Cingular’s 3G network. In my tests, MobiTV came pre-loaded on the devices, letting me simply select it from a list to start watching streaming content.

On the Cingular 8525, a smart phone running the Windows Mobile 5.0 operating system, I browsed through a guide until I found The Oxygen Network. The Isaac Mizrahi Show, not a favorite of mine, was just ending. It was followed by a quirky game show called “Can You Tell?”

MobiTV streams two types of programs: Live and Made for Mobile. Live shows are like those on your regular TV though slightly delayed and with different commercials in the local ad slots. I watched MSNBC’s “Hardball With Chris Matthews” using MobiTV and my regular TV, and an interview with Mia Farrow started about a minute earlier on my TV than it did on my mobile device.

Made for Mobile channels include special MobiTV content, such as music-video channels, or content for certain channels that MobiTV stitches together to show in a better format for mobile. The latter is the case with ESPN; in 15 minutes, I watched clips about football, Nascar, baseball, boxing and basketball with only a few quick commercials. In these snippets, however, lips weren’t synched with the audio.

I often opted to view content in full-screen mode, which, in 10 seconds, alters the image to take over the whole screen in horizontal view. A few times, while watching full-screen view, my on-screen content froze and had to restart in the regular view.

MobiTV says that using its service to watch programs saps battery at a rate equal to that of voice calls.

People who use digital video recorders at home to pause or rewind live TV will be disappointed to find you can’t do that with MobiTV. The company is hoping to offer these capabilities in the future. But because of the smaller screen, you probably won’t want to watch your mobile screen for as long as you would a regular TV, reducing the need to pause and rewind.

MobiTV’s services will never replace your home-entertainment center experience. But the ability to watch TV on your phone is a great way to stay plugged into news and entertainment. Just be sure that you’re using a fast network and a generously sized screen.

Everybody wants to be your cellphone company. It’s not just the traditional carriers, like Cingular or Verizon Wireless, that aim to provide wireless phone service. New brands, like ESPN and Helio, are entering the cellphone market. These new entrants don’t have to invest billions in building nationwide networks. They simply rent large chunks of capacity on existing networks, mainly Sprint’s, and then resell voice minutes and other features to consumers under their own brands, complete with their own phones, their own billing and their own customer service. They are called Mobile Virtual Network Operators, or MVNOs.

Disney Mobile offers a $59.99 Pantech cellphone (far left) and a $109.99 LG Electronics cellphone (middle) for use with its Family Center programs, which help parents keep tabs on their children’s cellphone usage. The Family Locator feature (above) uses GPS to locate children.

The latest MVNO is Walt Disney Co., which believes it can leverage its famous brand, and carve out a niche, with a “family friendly” cellphone company called Disney Mobile. The idea is to sell phones and services that make it easy for families to stay in touch while giving parents easy control over their kids’ cellphone activities.

These Disney cellphones allow parents to limit how many minutes their kids can use, with whom they are talking and when they use their cellphones. A parent can even learn where his or her child is using a GPS locator. Yet they do meet another need: giving kids a way to stay in touch with a phone that looks normal, even a little cool.

We’ve been testing Disney Mobile and, overall, we think it’s a smart idea. The phones were easy to operate without reading any directions, and restrictions can be set using the parent’s phone itself or the www.disneymobile.com Web site. We think it’s a good thing for parents to be able to set limits on kids’ cellphone privileges, and these phones offer a no-nonsense way of doing so.

But there are three big downsides to keep in mind. First, Disney Mobile is a cellphone company, not just a phone or a feature, so you have to switch your family from its current carrier and phones, or at least add one or more new contract and phone. Second, the company is new and small and offers just two phone models, not the dozens its rivals sell. Third, it runs on the Sprint network, so, if your Sprint coverage is poor, Disney Mobile won’t be a good choice.

This isn’t the first effort to make a restricted cellphone for kids. Over a year ago, we tested Firefly Mobile Inc.’s kid cellphones — tiny, glowing gadgets with only five buttons that were ideal for young kids who aren’t ready for cellphones with numeric keypads. The Disney Mobile phones are aimed at the next age group of “tweens” on up to teenagers, who would rather die than be caught using the odd-looking Firefly unit.

These phones are offered in two brands and prices: the $60 Pantech DM-P100 cellphone with a digital camera and the $110 LG Electronics DM-L200 phone with a digital camera and camcorder. (These prices require a two-year contract.) Both are flip phones with color screens and full numeric keypads, and they look and operate like regular cellphones. Disney-related themes like those from the movies “Cars” and “Pirates of the Caribbean” illustrate the navigational menus in each phone.

Voice and data plans can be purchased for individuals or families; family plans include two lines and additional lines can be added for $10 each. Plans range in monthly price from $40 to $250, but all include five free GPS “locates” per month. Neither phone can use Sprint’s latest, high-speed network for Web surfing and email. They are based on older technology.

Using the phones was easy. When you buy them — either from the Disney Mobile Web site, by calling 1-866-DISNEY2 or at kiosks in malls around the country — the phone’s owner is designated. A phone can be configured either as a parent’s phone or a child’s phone, even though they are physically identical. The parent’s cellphone has privileges and features that the child’s cellphone lacks.

A special Family Center menu within the phone offers four parental features: Family Locator, Family Monitor, Family Alert and Call Control. Another option within this menu called Shop Family will eventually offer various applications that compliment the Family Center programs; as of now these aren’t yet available.

We selected Family Locator on our parent phone (child phones can’t access this section), chose the name of the child whose phone we wanted to find and were asked for our four-digit PIN. In one test, after waiting for about 20 seconds while the screen read “Locating,” we received a message and map accurately finding our child-designated phone. It said the child’s phone was “Near [1707-1773] K St. NW, Washington, DC,” and said that was within 40 yards of the actual location.

But during other tests, Disney experienced problems with Sprint changing its network configuration, and we weren’t able to receive GPS information about our “child’s” cellphone. Disney fixed this after almost a whole day, but we wondered about parents who might have used the Family Locator during this outage, panicked to find their kids.

The Family Monitor section lets parents set allowances or view usage for each child’s voice, text, pictures and downloads. Parents can set allowances, see how much allowance a child has left in each section, and how much has already been used up. We noticed that the data for each updated whenever we closed and reopened the Family Monitor section.

The Family Alert section is filled with canned text messages that a parent or kid — each phone is set up accordingly — might send to one another. The parent’s quick alerts include “Can U get a ride?” and “Call me when U can,” while the child’s include “Can I hang out?” and the ever popular “What time is dinner?”

We easily sent these messages from one phone to the other by selecting them and hitting Send. The receiving phone got the incoming message, labeled as a “Family Alert!” so as to distinguish it from other messages. Unlimited intrafamily messaging is included in each plan.

All three of these sections can also be accessed on a computer at the www.disneymobile.com Web site, where you can see more details about each after entering log-in credentials and a PIN.

Call Control, the fourth section within Family Center, must be set up on the Web site. After you choose a phone, you can go through a simple chart to designate when your child can use his or her phone according to times and days of the week. Below this chart, a section lets you enter Always On numbers that the child can always call regardless of Call Control restrictions, such as 911 and numbers of relatives. Likewise, a section of Prohibited Numbers blocks all communication with certain numbers, including receiving or making calls and text messaging.

We restricted the child’s phone during certain times of the day, and when we tried to make a call from that cellphone during those times, it didn’t go through.

Disney Mobile is good news for parents who have had a hard time cracking the whip on cellphone usage and bad news for kids who sneak calls at all hours of the night or who run up their phone bills with text messaging. If you’re looking for a way to keep better tabs on your family’s cellphone usage, this system works well.

The cellphone — or, more accurately, the device formerly known as the cellphone — is getting to be more and more like a little portable computer. High-end models, known as smartphones, can handle large volumes of email, complete with attachments; surf the Web at high speed; view and edit Microsoft Office documents; take decent pictures; and play back music and videos.

To manage these laptop-like tasks, they come equipped with faster and faster processors; more and more internal memory; expansion slots for increasingly spacious memory cards; and small, but usable, keyboards, instead of mere phone keypads.

We’ve been testing two new such phones. One, from Palm Inc., is an improved model of the Treo, which has long been our favorite smartphone. The other, an entirely new design from Motorola Inc., manages to pack most of the Treo’s functionality into a much thinner and lighter body, at half the Treo’s price.

The new Palm model, called the Treo 700p, uses the Palm operating system and is being sold by both Verizon Wireless and Sprint Nextel Corp. for $399, with a service contract. The Motorola challenger, called the Q, uses Microsoft’s Windows Mobile operating system and is being sold by Verizon for $199, with a service contract.

The Q is the bigger news here. In the tradition of Motorola’s RAZR phone, the Q is a sleek, handsome devil. It demolishes the two biggest problems with smartphones like the Treo: They are bulky and expensive. The Q is a little wider than the Treo 700p, but it’s just half as thick and, at 4.06 ounces, is more than one-third lighter.

Unfortunately, its Microsoft software is much clumsier than the Treo’s Palm software, degrading its utility. Also, the Q’s screen is lower-resolution than the Treo’s and slightly smaller, and its battery life as a phone is weaker than the Treo’s. While the Q keyboard is larger than the Treo’s, we actually found it worse for typing.

Still, the Q is a decent solution for light email users and for those who have avoided a smartphone due to bulk and cost. We assume that, at $199, the Q will sell well and will challenge the Treo and BlackBerry in the marketplace.

However, we still prefer the Treo for serious users of mobile email, Web and Office. And the new model, with greater speed and other enhancements, only adds to the Treo’s strengths.

Both of these phones run on the new, broadband-like EV-DO data networks offered by Verizon and Sprint, so they are actually practical for Web browsing and for downloading big email attachments. In our tests, both registered speeds of between 200 and 500 kilobits per second, compared with about 70 kbps for the older Sprint and Verizon networks. Neither phone has Wi-Fi wireless capability.

The new Treo 700p is essentially the same as the Treo 700w introduced a few months back, except that the “p” model uses the Palm operating system, while the “w” model uses Windows software. Like the 700w, the newest model has a squarer shape than that of the older Treo 650. It also has bigger, better keys than the 650, roughly twice the usable internal memory and a higher-resolution 1.3-megapixel camera.

Also, the 700p now has — built into its memory — the excellent Documents To Go program from DataViz, which allows you to view, and in some cases edit, Microsoft Word, Excel and PowerPoint documents and Adobe PDF documents.

The main advantage of the 700p, however, is its ability to use the high-speed EV-DO network. And the new Treo can be used as a modem for a laptop, either via a USB cable or a wireless Bluetooth connection.

In our tests, over a couple of weeks, the Treo 700p performed well. Web browsing was a pleasure at the new high speeds. Our only complaint was a short but annoying lag in displaying the text of emails and in performing certain other operations. Also, our test unit crashed twice and had to be restarted. (It didn’t lose any data in the crash.)

The Q is a mixed bag. Its hardware is elegant. Its software is annoying, often requiring two clicks to do what takes one on the Palm.

Motorola chose a more stripped-down version of Windows Mobile software than the one used on previous keyboard phones, and it does work better one-handed. But it still requires many of the extra steps of its Windows sibling and yet lacks the touch screen and built-in Office programs of other Windows-based smartphones.

In our tests, we found the Q easy to carry, but often irritating to use. Things like muting the phone, locking the keyboard and even playing the built-in solitaire game took much more effort than performing the same tasks on the Treo.

The Q has four navigation buttons positioned below the screen like the Treo; like a BlackBerry, it has a scroll wheel and back button on the right edge. The Q’s keyboard has more space between each key than most smartphones, but the rounded shape of the keys themselves makes them uncomfortable to use for more than a few sentences of email.

The familiar green Send and red End keys are prominently located just above the keyboard, and number keys are distinguished in black. We chatted away using the Q’s phone, and it worked well on voice calls.

Special designated Back and Home keys are next to the Send and End keys, and two other buttons enable direct access to email and the Q’s digital camera.

We set up email accounts on the Q using EarthLink and Hotmail.com, but Windows Mobile software really started to get annoying while we were navigating through our email. Performing a task as simple as deleting a message requires two steps — selecting Menu, then selecting Delete — and we couldn’t find any way to highlight and delete a group of emails.

By contrast, on the Treo, using the major email programs, you can delete an email with one click and even clean out a whole inbox with a couple of clicks. This may not matter much to people who get little email, but for heavy users, it’s crucial.

We also had trouble with attachments on the Q. While we successfully received some pictures and documents, a test series of four emails, each with a different type of document attached, failed on the Q. On both of our test Q units, using two different email services, the four attachments simply disappeared, even though they came through fine on the Treo and on Windows and Macintosh computers.

Viewing Microsoft Office and PDF files on the Q is a more cumbersome process than on the Treo, and the files can’t be edited on the Q.

The 320×240 resolution on the Q’s screen is 25% lower than that of the Treo 700p, which has a 320×320-resolution screen. Many things — Web sites, photos, attachments — just didn’t look as good on the Q compared side-by-side with the Treo. The Q’s built-in 1.3-megapixel digital camera captured videos and still shots without a problem, but the view on our screen was cluttered by information bars at the top and bottom.

You might like the $199 Motorola Q because of its price tag or striking design. If you don’t use email too much, or if you’ve never used another smartphone, you might not miss the more user-friendly features that the Treo 700p has to offer. We wish that the sleekness of the Motorola Q could be combined with the intuitive features of the Treo 700p. For now, we’ll stick with what works best — the newest Treo.
