It all started with the CDMA phones but then the GSM phones started coming out slowly. The Gsm phones allow you to use SIM cards in them which is very convenient for people whenever they want to change their number or carrier, they don't need to get it registered for it.

GSM is an advanced network superior to that of CDMA. GSM is required for all the 3G and 4G wireless applications that you see today, such as those for iPhone.

Most likely you are not only hearing about those, you own one. GSM phone is the standard for mobile phones. It works by receiving and sending high frequency radio waves.
