What is GSM and CDMA?
The majority of carriers, such as AT&T and T-Mobile, use Global System for Mobile communication (GSM) technology. GSM phones have a SIM card that stores your account information and, if you choose, your phone book. When you switch to a new phone, you can activate it by simply removing the card from inside the old phone and inserting it into the new one. Some major carriers, such as Sprint and Verizon networks, mainly use Code Division Multiple Access (CDMA) technology. These phones do not require a SIM card and are activated directly by the carrier.
What is an Unlocked cellphone?
Most cell phones are designed to use a SIM card which is issued by a carrier and provides cell service by activating any phone into which it is inserted. A locked phone will only recognize a SIM card from a particular carrier. The "lock" is a software setting that keeps the cell phone "loyal" to one carrier. If the cell phone is unlocked, it will recognize a SIM card from any carrier. An unlocked cellphone can work with most SIM cards and/or GSM service providers. It also allows you to switch carriers without having to buy a new phone.
