When shopping for a cell phone, it's often a good idea to choose your carrier before you choose your phone. One very important factor is the technology your carrier employs. Almost all carriers use either Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA).

GSM is the dominant technology worldwide, but CDMA is more popular in the United States. The main difference between the two is whether you plan to travel abroad. There's little CDMA coverage in most parts of the world. Thus, GSM is probably preferable if you travel overseas a lot. CDMA may be more practical for people who tend to stay in the United States. GSM phones employ a chip, called a SIM card, which can be removed and plugged into a different phone. Some CDMA phones are now compatible with GSM networks to enable international calls.

Different carriers offer different service plans. Determine which is best for you; depending largely on how often you plan to use your phone, how often you might travel, and how often you might use your phone for international calls. Different carriers offer different phones. Some have more features than others; some will fit your hand better; and some will look nicer than others. It's largely a matter of personal preference in this regard.

Most people use their cell phones mainly for local calls, so look for the carrier that offers the best reception in your area. If you're on your phone a lot, choose a carrier that offers the best plan for unlimited use at any hour. If you rarely use your cell phone, you might prefer a pay-as-you-go plan. Choose a carrier that will allow you to change your plan if your usage changes.
