ABSTRACT:
A portable telephone for communicating with a base station connected to a telephone network has a communication control unit for controlling communication through the base station, a memory for storing control information for each area in which the telephone can be operated, together with a code of each area, and wherein the communication control unit includes a discriminator for discriminating the area code included in a control signal which is transmitted from the base station. The control information for the area of the area code which the discriminator has discriminated is read from the memory so that the communication control unit can make the corresponding communication control in accordance with the control information.
