GSM is a mobile phone technology that uses TDMA (Time Division Multiple Access). GSM stands for Global System for Mobile communications. The competing system is CDMA (Code Division Multiple Access). GSM and CDMA are not compatible systems. If a phone is designed for GSM, it will not be compatible with CDMA and vice-versa.
