How to Buy a Cell Phone

Buy Cell Phone

These days, smartphones get the entire phone, but the vast majority of handsets sold in the U.S. are actually feature phones: camera phones, music phones, rugged phones, messaging phones, or just plain voice phones.

Few tools of modern technology have become as prevalent as the cell phone, which allows you to be in touch (almost) all the time, (almost) anywhere. And you can do more than just talk–today’s phones let you send and receive e-mail and text messages, surf the Web, and play music and videos.

Unlike smartphones, feature phones are a matter of “what you see is what you get.” They don’t receive magical software upgrades or run thousands of additional apps, as does the iPhone, for example. That doesn’t mean they only make calls, though you can find phones that only make calls, if a basic phone is what you want. But most feature phones include some combination of a camera, a basic Web browser, e-mailing and text messaging apps, and music and video players.

Ready to find your phone? Here’s what you should consider before you , Buy Cell Phone, start shopping and we’ll walk you through what you need to know

Buy Cell Phone – Specs Explained

While a cell phone can make your life easier, just getting one can be a huge hassle. When you look at handsets and service plans, the sales reps may bombard you with a ton of terms and restrictions.

The two most important questions to ask yourself before you decide on a phone and plan are, “How much will I use the phone?” and “Where will I use it?” Those two questions will help you determine how many minutes you need and whether to go with a local, regional, national, or international plan.

The service meter starts running the minute you place and receive calls. The most common plans are national plans, which allow you to call from anywhere in the United States (and perhaps from some parts of Canada) without additional charges. You may also be able to sign up for a local service plan (one that allows you to make and receive calls from within your local area without so-called roaming charges being added) or for a regional plan that allows you to call from a wider area without incurring additional charges. If you travel overseas, look for an international plan that lets you use your world phone both stateside and in several other countries.

Many companies require that you buy a phone from them when you sign up. Some offer great discounts when you do so. In some cases you can buy the phone from a third party and sign up for service with the carrier of your choice.

Buy Cell Phone – Specs

Because you’ll be carrying the phone, its weight and size are fairly important factors to consider before you Buy Cell Phone. Most cell phones weigh from 3 to 6 ounces; generally, the more expensive a phone is, the smaller and lighter it is. (Smartphones with QWERTY keyboards, however, are an exception to this rule; they tend to be bulkier and heavier than standard cell phones.)

Battery life is another important factor Buy Cell Phone, since it determines how long you can go without recharging the phone, and you don’t want to be stranded with a dead battery. Talk-time battery life can range from little more than 1 hour to over 10 hours, depending on your handset. A phone that supports a 3G network is likely to have a shorter battery life than a non-3G phone. “Standby battery life” refers to battery life while the phone is on but not in use. Vendors will estimate both talk-time and standby battery life, but their estimates do not always reflect real-world usage.

Today’s phones let you do more than just talk. You can send and receive instant messages and even listen to songs or watch videos after downloading them. You need to take into account what you’d like to do with your phone before deciding on the right handset for you. Most low-end phones support sending and receiving text messages, handling basic e-mail chores, and doing limited Web surfing. More low-end phones are adding features like built-in cameras and music playback, but if you want faster or more-advanced Web access, video playback and recording, or GPS functionality, you’ll probably have to spring for at least an average or higher-end cell phone. And if you’re looking for a phone that will let you view and/or edit Office documents, consider a more-advanced smartphone.

Choosing among single-, dual-, tri-, and quad-band phones isn’t critical for most users. The more bands a phone supports, the more frequencies it picks up. Quad-band phones, as their name suggests, operate across four frequency bands. As a result, theoretically, they provide better coverage than tri-, dual-, or single-band phones.

Buy Cell Phone – Choose Your Carrier

Cell phones are more than just convenient communication tools: They allow you to check e-mail, sync with the calendar and contacts on your PC, dial a number by the sound of your voice, surf your favorite Web sites, take photos, play games, send text messages, view and edit documents, listen to music, and more. But choosing a phone–and the service plan to go with it–requires some legwork.

Your choice of phone may depend on your choice of wireless service provider. If you’re shopping for a carrier, you first need to figure out which carrier offers the best coverage and monthly service plan in your area. Then you’ll have to select a phone from the assortment that your chosen service provider offers. With the exception of a few handsets, most phones work only on one provider’s system because carriers have mutually exclusive networks, and many carriers lock their phones so you can’t take the same phone to another provider.

The third generation of mobile communications technology, commonly called 3G, is now more widely available. It’s supposed to boost data-transfer performance to 2 megabits per second from the more common data-transfer rate of 19.2 kilobits per second, and is particularly handy if you use a phone to wirelessly access data such as e-mail, text messages, and the Web.

Though the availability of 3G service has improved, it remains a mixed bag outside most major metropolitan areas. Sprint and Verizon Wireless use the Evolution Data Optimized (EvDO) network, which offers average download speeds of 400 to 700 kbps and potential maximum download speeds of 2 mbps. AT&T and T-Mobile support a 3G network called HSDPA (High Speed Downlink Packet Access), which is available only on select handsets. (AT&T’s HSDPA is also available for use with PC Cards.) In theory, HSDPA can reach download speeds of 3.6 megabits per second; in actuality, it delivers average download data rates of 400 to 700 kbps with bursts to more than 1 mbps. AT&T is currently upgrading its network to support HSDPA 7.2, which can deliver download speeds of up to 7.2 mbps; the upgrade won’t be complete until 2011, however. While more phones are offering support for HSDPA, many AT&T and T-Mobile phones still support EDGE (Enhanced Data rates for Global Evolution), which promises data transmission speeds of 384 kbps, and GPRS (General Packet Radio Service), with an average speed of 40 kbps but the capability to go up to 115 kbps.

Buy Cell Phone – Key Phone Features

Wireless standard: World travelers are more affected by wireless standards than are users based strictly in the United States. Most of the world uses networks based on the GSM (Global System for Mobile communications) standard. U.S. carriers, however, use a variety of networks in addition to GSM. U.S. carriers work on the CDMA (Code Division Multiple Access), TDMA (Time Division Multiple Access), iDEN (Integrated Digital Enhanced Network), GPRS (General Packet Radio Service), EDGE (Enhanced Data rates for Global Evolution), and/or EvDO (Evolution Data Optimized) standards. AT&T runs on the AMPS, EDGE, GSM, GPRS, and TDMA networks. Sprint Nextel uses the iDEN network exclusively. Sprint and Verizon Wireless run on CDMA and EvDO. T-Mobile supports GSM and GPRS networks. It is important to note that while AT&T runs on both GSM and TDMA networks, the services and the phones that use them do not interoperate.

Band support: The more radio bands a phone supports, the more frequencies it picks up. Quad-band phones, as their name suggests, operate across four frequency bands. Theoretically, they provide better coverage than triple-, dual-, or single-band phones. These so-called world phones are compatible with four GSM frequencies–850 MHz (prevalent in the United States), 900 MHz (prevalent in Europe), 1800 MHz (prevalent in Asia), and 1900 MHz (also available in the U.S.). As a result, they function around the globe. You can also find tri-mode phones that work on two digital frequency bands in addition to an analog network, a particularly handy feature if you travel to rural areas.

Wi-Fi support: A phone that can connect to Wi-Fi hotspots enables you to surf the Web or transfer data at much higher speeds. Even if your phone supports 3G networks, you may want Wi-Fi support, too, as it tends to be faster and more reliable than cellular networks. It can be cheaper, too, since surfing on a Wi-Fi network doesn’t require using your carrier’s service.

Design: You can choose among flip-open, clamshell-style phones; nonflip, candy bar-style phones; slider-style phones that–obviously–slide open; and swivel phones that twist open. Low-end flip phones may lack a separate caller ID screen, but many of today’s phones sport dual screens–a small, external LCD on the cover plus an internal display. If you buy a nonflip phone, make sure it has a keypad lock that prevents inadvertent dialing–a helpful feature when you put the phone in a pocket or bag.

Whichever type of phone you choose, check its ergonomics. Is it comfortable against your ear, and can you hear callers without constant adjustment? Can you use the phone with one hand? Consider hands-free use: Can you comfortably hold the phone to your ear by scrunching your neck and shoulder? Also, look for the placement of the headset jack–a jack located on top of the phone is often more convenient than one located on the side.

Size and weight: Part of what makes a phone easy to use is its portability. A typical standard cell phone weighs less than 4 ounces, and cell phones continue to get smaller and slimmer than ever. Smartphones with full QWERTY keyboards, such as a Palm Treo or BlackBerry device, tend to be a bit larger, which you should keep in mind if you plan to use one for long phone calls.

Battery life: Most new phones allow at least 4 hours of talk time and 2 to 6 days on standby. Some phones can last up to 14 days or more on standby. Keep in mind that several factors affect battery life; high-speed 3G networks tend to be power-hungry, for example, and the phones that support them often have shorter battery life. The signal strength of your cellular service also has an effect, since a phone that constantly searches for signals will run itself down quickly. Depending on the phone, recharging the battery should take about an hour or longer. When you buy a phone, consider optional accessories such as a higher-capacity battery and a portable charging adapter for use in a car.

Screen: If you intend to send and receive text messages, surf the Web, or use the phone’s organizer, make sure the screen is up to snuff. Make sure it’s big enough for you to take full advantage of the phone’s features. If you’re going to surf the Web or edit office documents on your phone, a screen that’s less than 2.5 inches diagonally will feel very small.

The screen’s contrast and backlight strengths are also important. The phones we’ve seen show marked differences in viewing quality. If your phone allows you to adjust such settings, you can make text and graphics easily viewable–even in bright places.

You also should consider the screen’s resolution. The higher the resolution, the better the screen will look–an important consideration if you plan on using your phone to watch videos or look at photos.

When the first-generation iPhone, it touched off a touch-screen frenzy. Since then, more and more phones have come out with touch screens. If you’re looking for such a phone, keep in mind that not all touch screens are created equal. Some–like the iPhone’s screen–support multitouch, which means they can register more than one touch point at a time. This technology allows you to pinch and grab the screen to zoom in and out on a Web page, for example. Other phones support single touch only, and can register only one tap at a time. Some touch screens also offer a type of feedback–either a slight vibration or a sound–when they register your touch, which can prevent you from tapping needlessly. Finally, consider ease of use: How simple is it to scroll through items on a particular touch-screen menu? Can you adjust the sensitivity of it to your liking?

Voice communications and organizer: Mobile phones bombard you with call-management features–voice-activated calling, voice recording, phone books, call histories, speed dialing, and so on. Enabling some of the features (such as caller ID, call waiting, and three-way calling) depends on your service plan. Most phones also provide security features that can restrict incoming and outgoing calls, lock the keypad, and protect or mass-delete phone book entries. Many handsets also provide a speakerphone. Some even function as two-way radios, connecting you with others on the same carrier; and in many cases, such communications don’t count as airtime–a great benefit for IT personnel and other roving staff.

If you want to talk on the phone hands-free (a must if you use the phone while driving), look for a model that comes with a headset or an earphone. If you don’t want to mess with cords, consider a phone that supports Bluetooth, which allows you to pair the device with a wireless Bluetooth headset.

Wireless data: Nearly all cell phones are capable of sending and receiving e-mail and instant messages, downloading custom ring tones and simple games, or connecting to the Internet (sometimes merely by way of a minibrowser that’s designed to work best with text-only versions of popular sites like Amazon, Google, and Yahoo). Such features, however, are heavily dependent on your provider and your service plan.

Going online while you’re waiting for the elevator is a cool idea, but most phones connect at slow speeds: only up to 115 kbps on a GPRS network and up to 384 kbps on EDGE; 3G networks, such as EvDO and HSDPA, provide faster connections at up to 2 mbps. A Wi-Fi connection can be faster and more reliable than a carrier’s data network, but you must be within range of a wireless hotspot in order to use it.

Keypad: If you can’t figure out how to use certain functions on a phone pretty quickly (with or without consulting the manual), try another; remember, though, that if you’re looking at a phone that packs a lot of features, you should spend some time learning how to use them. Regardless, the keypad layout and menu system should be intuitive. The buttons should be responsive and easy to press. Check out the navigation buttons on the keypad. A joystick-style knob on some phones can make navigating menus quick. Most handsets come with up/down and left/right arrow keys. Buttons that protrude slightly are much easier to use than flat or recessed keys.

Many phones come with a small QWERTY keyboard. The tiny keys may not suit everyone, but they can save you a great deal of time if you plan to use your phone for sending e-mail messages and editing office documents. Even very small QWERTY keyboards can be much easier to use than a software-based keyboard on a touch-sensitive screen.

Operating system: If you’re looking to do more than make calls and send text messages with your phone, you should consider the platform on which it runs. The mobile operating system you choose will greatly affect the capabilities of your phone. Smartphones that run the Windows Mobile OS, for example, usually come with mobile versions of the Microsoft Office suite, so you can view and edit documents when you’re away from your PC. Windows Mobile is available on a wide range of handsets from all carriers, so you’ll have plenty of choice in hardware. BlackBerry smartphones run the BlackBerry OS, which has recently been updated. It sports a newer, more modern look and is easier to use than in the past. Various third-party software titles are available for BlackBerry phones, and with the launch of BlackBerry App World (an on-phone download catalog), we should see even more. The Palm OS is not as widely available, but it retains a devoted follow ing, largely because of its easy learning curve; you’ll also find a good deal of productivity software available for Palm OS-based phones. The Symbian platform, which is available on most Nokia smartphones, is not as user-friendly, but it supports a range of business and productivity apps.

Newer platforms include the modified version of the Mac OS that runs on Apple’s iPhones. While the iPhone doesn’t ship with any true office applications, it does include easy access to Apple’s App Store, where you can find an incredible range of applications–for work and play–available for download. Another new platform is Google’s Android, which is available on relatively few handsets so far, such as the T-Mobile G1 smartphone. Android phones include access to their own marketplace for downloading applications, but the selection there isn’t as vast as that at Apple’s App Store–though it is growing. The newest platform is Palm’s WebOS, available on the Palm Pre. WebOS offers many refinements not found on other mobile platforms–including the ability to keep more than one application at a time open for multitasking. WebOS also offers its own application catalog, but the platform is still quite new, and the sel ection of applications is sparse.

Next, Buy Cell Phone, What Are Your Feature Priorities?

Because feature phones do almost everything, you should decide what capabilities you need or want most. Start narrowing down your choices by first ranking the five major categories of features in order of importance: voice, messaging, camera, media playback, and Web/GPS/games/miscellaneous. Once that’s done, you’ll be able to concentrate on a filtered-down selection of feature phones.

If you’re big on text messaging, you want to focus on messaging functionality. If you’ve got a small child, a camera is probably important. If you want to ditch your iPod, keep an eye out for good media features.

Since it’s a given that you want your calls to sound good, you may feel you should focus mainly on voice rather than other features. You don’t need to worry too much about that. The vast majority of phones sold today have solid voice capabilities. Paying attention to the other features you like, and then double-checking to make sure the phone you choose delivers on voice quality, makes it easier to sift through a long list of handsets.

Voice ; Reading reviews and trying out a phone before you buy it are the best ways of gauging voice quality. Most phones fit into a broad middle range of reception and sound quality. But you can still find phones that are uncommonly loud or have a lot of “side tone,” that is, the feedback of your own voice in your ear (which can help you avoid yelling into the phone).

If you’re primarily interested in voice and you’re looking at AT&T or T-Mobile, focus on 3G phones. Those carriers’ 3G networks offer superior voice quality to that of the 2G networks. The major downside is that AT&T and T-Mobile 3G phones have about half the battery life of 2G phones.

Important voice features to look for include no-training voice dialing, Bluetooth headset support, and a standard (2.5mm or 3.5mm) wired headset jack.

Yes, there are still super-simple phones out there that basically only make calls. The Sanyo PRO 200 on Sprint and the Samsung Knack SCH-U310 on Verizon Wireless are two high-quality voice-only phones.

Messaging; Texting, e-mail, and IM capabilities are showing up in more and more phones these days. If you intend to text often, get a plan with unlimited text messaging—it’ll likely save you money in the long run. The best phones for heavy messaging have full QWERTY keyboards, like Verizon Wireless’s Samsung Alias 2 SCH-u750 and AT&T’s Pantech Matrix C740. You may also want to check to ensure that the phone supports threaded texting, a feature that groups together all text messages from the same sender. The Alias 2 supports threading, but relatively few other phones do.

Don’t expect e-mail or IM on feature phones to give you a full smartphone experience. Feature-phone e-mail programs typically download your e-mail in text-only mode, without attachments, and feature-phone IM programs often won’t let you access your AIM buddies. Sprint’s e-mail program, on handsets like the Samsung Rant, is the best of the bunch, supporting multiple accounts and some attachments.

Camera; The great thing about a phone with a camera is that you always have it with you, so you end up photographing moments you would have otherwise missed. Camera phones are becoming as good as low-end digital cameras, in many cases taking print-worthy photos.

If you’re interested in taking shots with your camera phone at all, don’t settle for less than 2MP. Keep an eye on reviews to see which phones take washed-out, compressed-looking photos and which take bright, clear shots. It’s harder to find a good video phone than a good camera phone. If you want to post your videos online or burn them to DVD, look for a phone that takes 320-by-240-pixel videos, at 15 frames per second or better.

A few camera phones we’ve seen really stand out. The Motorola MotoZINE ZN5 and Samsung Memoir SGH-T929 on T-Mobile take 5MP and 8MP photos, respectively. The ZN5 has very little shutter delay. The Memoir takes somewhat better pictures, but you have to wait for them.

Media; If you want to get rid of your iPod, your best bet is one of Verizon Wireless’s phones with V CAST Music with Rhapsody; these sync with the powerful Rhapsody music program on Windows PCs. Otherwise, look for the many phones that sync with Windows Media Player. Mac users are pretty much out of luck for syncing music on feature phones—you’ll have to drag and drop your songs onto a microSD memory card.

You also want a phone with a 3.5mm headphone jack, so you can listen to your songs with standard music headphones. If you get a phone with a 2.5mm jack, or even worse, a proprietary one, you’ll need a clumsy adapter to use quality headphones. As an alternative, look for a phone that supports stereo Bluetooth wireless headphones. Verizon’s LG Chocolate 3 VX8560 is one example of a top-notch music phone, with a standard jack, stereo Bluetooth support, and access to Rhapsody.

Feature phones typically don’t make very good video players. They often can’t sync video with PCs and don’t come with software to convert video into the often-obscure formats they support. (If you’re a bit of a hacker, you can force your video into a phone-friendly format.) Look for a phone with a larger screen for video watching, like the LG Dare VX9700 for Verizon.

Web/GPS/Games/Etc; Some phones have decent browsers that display most Web pages; others only have basic WAP browsers. If you want to surf often on your phone, you may want to consider Sprint, since the carrier will let you install the third-party Opera Mini Web browser on its devices. Most current phones come with some variety of for-pay GPS capability—but be sure to get a handset with a loud speakerphone so you can hear the directions. Phones can play games, too. Verizon’s LG Versa VX9600, for example, is a great choice with its optional dedicated game pad.

And for the accident-prone, some phones, like AT&T’s Samsung Rugby or Verizon Wireless’s G’zOne series, are even ruggedizedor waterproof.
