Abstract

The invention discloses a mobile terminal with a card lock anti-theft function and a card lock anti-theft method thereof. The invention can send a card lock instruction to the mobile terminal through the mobile phone of the bound anti-theft notification contact person, so that the switch of the anti-theft module can be controlled The unit controls the card lock switch set at the working port of the SIM card interface circuit to be disconnected, making the SIM card interface circuit invalid and preventing others from using the communication function of the mobile terminal. The mobile phone of the bound anti-theft notification contact person sends an unlock command, so that the switch control unit of the anti-theft module controls the lock card switch to be closed and turned on, so that the SIM card interface circuit can work normally. The present invention can prevent others from using the user's mobile terminal to carry out fraudulent activities. It ensures the safety of the user's property, reduces the value of the mobile terminal in the hands of pickers or thieves, increases the initiative of the owner in the subsequent negotiation process, and increases the possibility of recovering the mobile terminal after it is lost or stolen.
