Mobile phone anti-theft method, device, system and mobile phone

Abstract

The application discloses a mobile phone anti-theft method, device, system and mobile phone. Through this application, when the user needs to take out the user identification module in the mobile phone, the processor generates the user identification module removal password input prompt information according to the user identification module removal instruction; after receiving the correct user identification module removal password, the processor sends The subscriber identity module fixing device transmits a fixation release command to release the fixation of the subscriber identity module, so that the subscriber identity module can be taken out.
