GSM
GSM stands for Global System for Mobile Communications and is an international wireless standard in use all over the world; in the US, AT&T and T-Mobile are the carriers that use GSM technology in their phones and networks.
Only GSM phones allow you to use a removable SIM card, or Subscriber Identity Module, a portable memory chip that makes switching phones easy by simply taking the card from one phone and putting it into another GSM phone. The card stores all your personal information and phone settings, so as soon as you put your SIM card into a new phone your contacts will be able to call you at the same number. When travelling internationally, you can also buy prepaid SIM cards that will work in your unlocked GSM phone (unlocked refers to a phone not bound to a specific carrier) and provide you with a local number -- all without the hassle of having to buy or rent a new phone overseas.
