A mobile communication terminal includes an IC card, a power supply, and a control section. The IC card stores an identification number. The power supply supplies power to the mobile communication terminal. The control section can set the mobile communication terminal to a communication possible state when the power is supplied from the power supply and an entered identification number is coincident with the identification number stored in the IC card. Also, the control section can set the mobile communication terminal to the communication possible state depending on a power down time period without an entering operation of the identification number when the supply of the power to the mobile communication terminal is stopped and then recovered. |
