GSM Technology

The GSM family of technologies has provided the world with mobile communications since 1991. In over twenty years of development, GSM has been continually enhanced to provide platforms that deliver an increasingly broad range of mobile services as demand grows.

Where the industry started with plain voice calls, it now has a powerful platform capable of supporting mobile broadband and multimedia services.

GSM is now used in 219 countries and territories serving more than three billion people and providing travellers with access to mobile services wherever they go.

The IMEI number is used by the GSM network to identify valid devices and therefore can be used to stop a stolen phone from accessing the network. CheckIMEI software show information about manufacturer, model type, and country of approval of a handset.
