Subsequently, the user again selects the second SIM by touch or key input in the SIM number display area 60-1, and then inputs a second PIN code 2xxx into the PIN code input area 60-2. After inputting the first PIN code and the second PIN code, the user presses a confirmation button to complete the input.

5B illustrates a display form of a PIN code input window when only one SIM is mounted in an embodiment of the present invention.

As shown in FIG. 5B, when only one SIM, for example, the first SIM is mounted in the terminal capable of mounting the dual SIM, the controller 180 displays the number of the second SIM in the SIM number display area 60-1. The area | region to perform is grayed out. In this screen display, the user inputs the PIN code for the first SIM using the same method as 5a.

Meanwhile, the present invention may perform the priority for the dual SIM in the PIN code input window 60. In general, the priority setting for the dual SIM is performed in a separate menu after entering the idle state by entering a PIN code.
