GSM, which stands for Global System for Mobile communications,

reigns as the world’s most widely used cell phone technology.

Cell phones use a cell phone service carrier’s GSM network by

searching for cell phone towers in the nearby area.

The origins of GSM can be traced back to 1982 when the Groupe

Spécial Mobile (GSM) was created by the European Conference of

Postal and Telecommunications Administrations (CEPT) for the

purpose of designing a pan-European mobile technology.
