CDMA stands for Code Division Multiple Access and is a major technological channel access method used in wireless telecommunications. It is different from GSM (Global System for Mobile Communications). Typically, CDMA handsets differ from GSM handsets and don't feature the use of a SIM card, though handsets supporting both standards are also available. The data services offered by CDMA providers are also different from those offered by GSM providers because of the different access methods used.
