1. A method of automatic country dependent operation of a mobile station capable of wireless communications in accordance with protocols of at least two different standards, comprising steps of: in each of a plurality of locations as a user of the mobile station roams, scanning one or more frequencies on which the mobile station expects to find signals of a mobile communication network with which the mobile station may be able to communicate; from each scanning, acquiring a signal of a respective mobile communication network in an area where the mobile station is operating or intends to operate; from each acquired network signal, obtaining at least one system identifier of the respective mobile communication network; at a first location wherein the obtained at least one system identifier comprises a mobile country code (MCC) in accord with a first of the protocols, using a first list or table stored in memory of the mobile station, mapping the MCC to an identification of a country in which the mobile station is operating or intends to operate; at a second location wherein the obtained at least one system identifier comprises a system identifier (SID) in accord with a second of the protocols, using a second list or table stored in memory of the mobile station, determining whether the SID maps to more than one identification of a country in the second list or table, and mapping a combination of the SID and a parameter of the acquired network signal to an identification of a country in which the mobile station is operating or intends to operate upon determining that the SID maps to more than one identification; and automatically adapting at least one operation of the mobile station responsive to the country identifications.
