GSM is a cellular network which stands for Global System for Mobile Communications whereas , CDMA refers to Code Division Multiple Access.
While using a GSM service, one can subscribe to any network service provider using the same mobile phone by just changing the Subscriber Identity Modules, and this facility is not available for CDMA users.
CDMA requires less power as well as little cell to cell coordination and as a result of which, it performs well even in the rural areas whereas, GSM requires more power and more cell to cell coordination compared to CDMA.
GSM users has the advantage of International Roaming but this facility is not available for CDMA users.
