GSM
GSM (Global System for Mobile Communications). A wireless communication system for cellphones than allows roaming over 170 countries using the same number. The system is evolving into 3GSM, EGSM (Extended GSM) and EDGE. This is the scheme most used in Europe. GSM uses time division multiplexing where each user gets a time slot on the same frequency.

If you have a T-Mobile, Cingular, or recent new M-mode type service with AT&T (American Telephone & Telegraph), then you have GSM service. GSM phones are not compatible with CDMA (Code Division Multiple Access) wireless.

In Canada Rogers and Fido are GSM.

GSM systems use encryption to make phone calls more secure. GSM operates in the 900-MHz and 1800-MHz bands in Europe and Asia and in the 1900-MHz (1.9-GHz) band in the United States. When you see phones advertised as 900,1800,1900 capable they they will work in both Europe and North America under GSM.
