Subscriber Identity Module, or "SIM" card, a device used to store information in mobile phones

Code division multiple access (CDMA) is a channel access method utilized by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne and CDMA2000 (which are often referred to as simply "CDMA"), that use CDMA as their underlying channel access methods.

Global System for Mobile communications (GSM: originally from Groupe Spcial Mobile) is the most popular standard for mobile phones in the world. Its promoter, the GSM Association, estimates that 82% of the global mobile market uses the standard

SIM stands for Subscriber Indentity Module for mobile phones stores service-subsriber key (IMSI) that used to identify a particular subscriber by the network service provider.

GSM stands for Global Satellite Medium
CDMA stands for code division memory access

In GSM phones, you can change the sim card whereas in CDMA phones the sim card is sealed. GSM phones cover less network compared to CDMA phones. If a tower is located at a distance of 2 kms GSM phones can catch network whereas in CDMA phones, a tower at distance of 5 kms can give good network coverage.
