The card has a ROM in which the identification information and password of a subscriber are stored in advance. The portable telephone set body has at least a radio section for transmitting/receiving a radio signal, and is used to perform originating and terminating operations. The card insertion detecting circuit detects insertion of the card in the portable telephone set body. The control section sets the portable telephone set body in a password input wait state when insertion of the card is detected by the card insertion detecting circuit and the power supply of the portable telephone set is turned on while the card is inserted therein, and sets the portable telephone set body in a wait state allowing originating and terminating operations only when a correct password is input in the password input wait state.
