I have recently seen many mobile users, but I noticed is that most of them clearly know what is a SIM card but they lack in knowing what exactly is its acronym! There are many mobile terms which come in our mouth as easily as if they were born there but the exact meaning of it remains hidden. So today I'm going to show you some of the most commonly used acronyms.

SIM - Subscriber Identity Module
CDMA - Code Division Multiple Access
GSM - Global System for Mobile communications
2G - Second Generation
3G - Third Generation
4G - Fourth Generation
WiFi - Wireless Fidelity
IMEI - International Mobile Equipment Identity

Hope you remember them now!
