Abstract: PURPOSE: A CDMA mobile communication service method for using a mobile terminal in several countries is provided to allow a user to simply use a mobile communication service in many countries at a reasonable telephone charge with only one mobile terminal. CONSTITUTION: A user of a mobile terminal(20) inputs a service request to a service subscription server(21)(200). The service subscription server(21) subscribes each mobile communication service desired to be used by the mobile terminal user(210) so that the mobile terminal user can be subscribed for the first mobile communication service of the first country(22) and the second mobile communication service of the second country(23)(211,212). The service subscription server(21) sets an NAM(Number Assignment Module) for using each mobile communication service by using a terminal electronic serial number of the mobile terminal(20) and the first and second terminal subscriber IDs(221,222) notified by each mobile communication provider(223). The mobile communication user uses both the first and second mobile communication services(22,23)(230). When the user is moved from the first country to the second country, he/she changes the existing NAM to the second NAM(240) to converting the mobile communication service.
