According to the second aspect of the present invention, the telephone number and location information of the destination wired telephone input by the input means based on the call charge system stored in the storage means. A call charge from the main body of the wireless telephone device to the destination wired telephone via the wireless telephone system corresponding to the position information extracted by the extracting means is calculated for each wireless telephone system, and Since the wireless telephone system corresponding to the cheapest telephone call charge to the wired telephone is automatically selected and the call is sent to the incoming wired telephone via this selected wireless telephone system, the wireless telephone When placing a call to a destination wired telephone via the system, connect to the wireless telephone system with the lowest call cost, taking into account the current location without placing an operation burden on the user Rukoto can, can be kept to a minimum and thus call charges by the user to bear.

According to the wireless telephone device of the third aspect of the present invention, the position information of the wireless telephone device main body extracted by the position information extracting device based on the call charge system stored in the storage device. A call charge from the main body of the radio telephone device to the destination radio telephone via the radio telephone system corresponding to the location information of the destination radio telephone is calculated for each radio telephone system. The system automatically selects the wireless telephone system corresponding to the cheapest call fee to the telephone, and calls the incoming wireless telephone via this selected wireless telephone system. When placing a call to the destination wireless telephone via, the user is connected to the wireless telephone system with the lowest call rate, taking into account the current location without burdening the user. Rukoto can, can be kept to a minimum and thus call charges by the user to bear.
