PROBLEM TO BE SOLVED: To shorten a processing time until a communication network is informed of the state information of a terminal after a starting, and to enable the simplifying of a process and the reduction of a cost in the case of a manufacture. SOLUTION: An antenna 21 and an RF section 20 conducts a radio communication by selectively using either of a plurality of frequencies. A USIM card recording at least an enterpriser discriminating information (a PLMN) and a subscriber discriminating information is fitted to a USIM module 25. A ROM 35 stores all softwares for carrying out functions related to each service provided by all communication enterprisers severally independently. A control section 28 reads a PLMN information from the USIM card after a power supply is turned on, and loads only the software corresponding to the PLMN information to a RAM 36 from the ROM 35. The control section 28 determines the frequency searched first after the power supply is turned on on the basis of the information described in the loaded software. COPYRIGHT: (C)2007,JPO&INPIT
