From Wikipedia:

GSM-900 and GSM-1800 are used in most parts of the world: Europe, Middle East, Africa, Australia, Oceania (and most of Asia). In South and Central America these countries use the following:

  • Costa Rica - GSM-1800
  • Brazil - GSM-850, 900, 1800 and 1900  (everything works here)
  • Guatemala - GSM-850, GSM-900 and 1900
  • El Salvador - GSM-850, GSM-900 and 1900
  • Colombia uses 850/1900

In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz. In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band. In the United States, regulatory requirements determine which area can use which band.
