GCF

GCF (Global Certification Forum) is a pool of mobile phone manufacturers, mobile network operators and test-service providers. Their aim is to secure the function of mobile phones according to GSM and UMTS standards by accomplishing standardised tests and a subsequent certification of the mobile radio unit.

GSM

The Global System for Mobile communications is, with its digital signalling and speech channels, the most popular standard for 2nd generation mobile phone systems used in the world. GSM's availability enables international roaming arrangements between mobile phone operators, providing subscribers the use of their phones in many parts of the world.
