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. If the received password for taking out the SIM is incorrect, the processor will not transmit the unfixing command to the SIM fixing device, and the SIM fixing device will keep fixing the SIM, so that the user cannot take out the SIM, preventing the user from The identification module is taken out at will to ensure that the mobile phone remains connected to the network, ensures that the mobile phone's location information can be transmitted normally, realizes the positioning of the mobile phone, and improves the probability of finding the mobile phone.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, in particular to a mobile phone anti-theft method, device, system and mobile phone. Background technique [0002] With the development of information technology, mobile phones have become an indispensable communication tool in people's daily life. Moreover, in addition to being used for communication, mobile phones can also store a large amount of social information, work logs and account information of the owner. Therefore, once the mobile phone is lost, it will not only bring economic losses to the owner, but also may cause information leakage of the owner. [0003] In order to reduce the loss caused by the loss of the mobile phone to the owner, most mobile phone equipment manufacturers set up a positioning system in the mobile phone when producing the mobile phone. After the mobile phone is lost, the location information of the mobile phone can be obtained through the pos...
