Dual-SIM mobile terminal and operation method for the same
First Claim
1. An operation method for a dual-subscriber identity module (SIM) mobile terminal, comprising:
- detecting, upon turning on the dual-SIM mobile terminal, whether a first SIM card and a second SIM card are installed in a first card socket and a second card socket;
storing a SIM identification information regarding the first SIM card if the first SIM card is installed in the first card socket;
storing SIM identification information regarding the second SIM card if the second SIM card is installed in the second card socket;
selecting and performing a boot procedure according to the number of installed SIM cards by;
performing the boot procedure based on the installed SIM card when a single SIM card is installed in a socket; and
performing the boot procedure based on a preset SIM when both the first and second SIM cards are installed in the sockets,wherein performing a boot procedure comprises;
inputting an identification signal to the first card socket or the second card socket;
detecting one of the first SIM card and second SIM card outputting a response signal associated with the identification signal; and
initializing the dual-SIM mobile terminal using the detected SIM card.

Abstract
A dual-SIM mobile terminal and operation method for the same are disclosed. The dual-SIM mobile terminal checks the number of installed SIM cards during booting, and activates and deactivates the SIM switching mode according to the identified SIM card information. The operation method includes: detecting whether a first SIM card and second SIM card are installed in a first card socket and second card socket; storing SIM identification information regarding the detected SIM card; and performing a boot procedure on the basis of the detected SIM card. In particular, the SIM switching menu is displayed in an activated or deactivated state according to the identified SIM card information. Hence, the user can readily identify the number of installed SIM cards and the availability of SIM card switching through display status of the SIM switching menu.
