<< Does anyone know what GSM frequency cellphone works for the various prepaid calling service? Do they used GSM 900/1800/1900 MHz or GSM 850/1900 Mhz? >> Vincente F
Believe the GSM frequency is the same for both prepaid and postpaid. *Orange* prepaid/postpaid works with GSM 900/1800/1900 cellphones. Lawrence
