First Claim
1. A cellular phone comprising:
- a plurality of mounting parts which allow the mounting of IC cards in which at least the country number of the contracting country and the own-station telephone number are stored;
a position information storage device that stores position information indicating the position where said cellular phone is located;
a selection device which makes it possible to select the IC card in which the own-station telephone number that is used for calling is stored from the IC cards mounted in each of said plurality of mounting parts;
a first determination device which determines, on the basis of the country number stored in the IC card selected by said selection device and the position information stored in said position information storage device, whether or not calling is to be performed by adding header information for accessing the exchange of the contracting country of said IC card; and
