Features
Here is a list of features that should be considered when looking for a cell phone:

    * Service plan
    * Mode
    * Battery type
    * Display
    * Included functions
    * Special features
    * Size
    * Price

Service Plan
Before you set your sights on a particular make or model of cell phone, you should decide on the service plan that interests you. Otherwise, you could find that the phone you want is not supported by the plan you need. See How Cell Phone Services Work to learn all about the service plans available.

Mode
Are you looking for analog or digital? Do you prefer PCS or cellular? TDMA or CDMA? If you have read How Cell Phones Work, then you know what each of these terms means. Look for dual mode/dual band phones if you travel a lot.

Battery type
Cell phones use two main battery technologies:

    * NiMH (nickel-metal hydride) - high capacity battery that provides extra power for extended use
    * Li-ion (lithium ion) - has a lot of power in a lightweight package but usually costs more than NiMH batteries

Note both the talk time and standby time when comparing phones. Also, check to see how long the battery takes to recharge and whether a rapid charger is available. Most cell-phone batteries are removable, but some of the smaller models have a built-in battery instead.

Display
All cell phones have LCD displays, but the specific features of the display can vary:

    * Size - A large, multi-line display is typically more expensive, but it's necessary if you plan to use the phone for wireless Internet.
    * Color vs. monochrome - Most cell phones have monochrome displays (16 grays), but a there are a growing number that have color. Cell phones with color screens need more memory and tend to be more expensive.
    * Reflective or backlit - Almost all cell phones have backlit screens, which are good for low-light conditions.

Included Functions
Most premium phones offer all of these features, while more economical phones may only have a few:

    * Phone directory
    * Clock
    * Calculator
    * Games
    * Personalized/custom sounds
    * Appointment reminder/calendar
    * Incoming-number storage
    * Automatic redial
    * Last-number recall
    * Mute/hold button
    * One-touch dialing/speed dialing
    * Voice-activated functions
    * Vibrate mode
    * Lock/alarm
    * Call forwarding
    * Multi-party calls
    * Hands-free headset/speakerphone
    * External volume/ringer control
    * Rapid charger/built-in charger
    * Car adapter

Special Features
Some cell phones have special features such as:

    * Text messaging
    * Wireless Internet
    * Modem function
    * PC synchronization
    * PDA
    * MP3 player
    * GPS receiver

When looking at phones with a headset or speakerphone connection, check to see if the plug is proprietary. If it is, then check the cost and availability of the headset or speakerphone. Also, all phones come with a charger, but not all of them come with a rapid charger.

Size
Think about how you plan to use the phone. Will it mostly be a car phone? Or do you plan to carry it in a pocket all day long? This will help you determine if that cheaper phone with the same features that weighs 10 ounces is a better deal than the one that only weighs 5 ounces but costs twenty percent more.

Price
If you are like most of us, price is always a consideration. Weigh the options carefully and make sure that you don't pay for features that you probably will never use. If you are not interested in wireless Internet, then you may not want to pay the extra bucks for a WAP-enabled phone.

Look Out!
There are a few things you should be aware of when buying a cellular phone:

    * If you travel a lot, will your phone work in a different state or country?
      This depends largely on whether your phone is analog, digital or both (dual-mode). With a digital signal, depending on your provider, your phone might work only over a certain region, or perhaps over your entire country. The problem is that there are several competing digital systems available -- and several different frequencies on each system. Ask your access provider for a map of exactly where the digital signal you will be accessing is available. If your phone is analog, it will probably work over most areas. However, when you use an analog signal, you are sacrificing a lot of the features and clarity that have become common with a digital signal. A dual-mode phone can utilize a digital signal when available, or switch to an analog signal if necessary, and is thus the best option if you travel a great deal.

    * Are you worried about radiation?
      There have been several studies done, with conflicting results, on the effects of cell-phone radiation on the human body. The amount of radiation emitted from most cell phones is very minute. However, given the close proximity of the phone to the head, it is entirely possible for the radiation to cause harm. If you want to be on the safe side, the easiest way to minimize the radiation you are exposed to is to position the antenna as far from your head as possible. Utilizing a hands-free kit, a car-kit antenna or a cell phone whose antenna is even a couple of inches farther from the head can do this most effectively.


    * How much are you paying for long distance?
      Many access providers have special rate plans going constantly, some offering "free long distance." Make sure you ask questions regarding exactly what they mean, how long the special rates last and what exactly is considered to be "long distance." Also, before you get yourself into a long-term contract, be sure to find out about any surcharges you might be held responsible for.
