Abstract:
1. A communication terminal comprising: a plurality of loading mechanisms into which a plurality of storage devices each storing an identifier concerning a communication carrier are loaded, each of the plurality of storage devices being capable of being detached from the communication terminal; a readout unit which reads out the identifiers, from the plurality of storage devices loaded into the plurality of loading mechanisms; a communication unit which determines the communication carriers based on the identifiers read out by the readout unit, and performs communication using the determined communication carriers; a generation unit which generates, in accordance with an address book registration instruction by a user of the communication terminal, address book information in which information of a communication partner of another communication terminal than the communication terminal is registered in association with identifying information for identifying an address of the communication partner and carrier information indicating a communication carrier of the communication partner, wherein each of the information of the communication partner, the address of the communication partner, and the communication carrier of the communication partner is set by the user of the communication terminal, the generation unit registering the information of the communication partner set by the user in association with the identifying information of the communication partner set by the user and the carrier information indicating the communication carrier of the communication partner set by the user; a memory which stores the address book information generated by the generation unit; a designation unit which designates a communication partner; a detection unit which detects a communication carrier corresponding to the communication partner designated by the designation unit from the carrier information registered in the address book information stored in the memory; and a control unit which detects the identifying information of the communication partner designated by the designation unit from the identifying information registered in the address book information stored in the memory and controls the communication unit to perform communication with the communication partner using the communication carrier detected by the detection unit based on the detected identifying information of the communication partner designated by the designation unit.
