Example Embodiment

[0023] First, explain the key steps of the present invention:

[0024] When the mobile phone is turned on, the anti-theft password is confirmed; then the mobile phone initializes the USIM card and reads out the IMSI for matching. Under normal circumstances, the phone is initialized and enters the standby state, and the user can set the anti-theft number. If the anti-theft password is entered incorrectly, the phone will be locked; if the IMSI does not match and the matching password is incorrect, the phone will be locked. After the above two situations are locked, the mobile phone completes initialization without the user's knowledge and enters the standby state, and periodically sends the IMSI number and mobile phone number of the current USIM card to the designated anti-theft number. The user can obtain the unlocking password from the database of the mobile phone manufacturer in the form of a phone call or text message. When the mobile phone is locked, the mobile phone can be unl...

Abstract

The invention relates to a method for guarding mobile terminals from thieves, which comprises the steps that: an IMSI code in a matched SIM/ UIM/ USIM card is pre-stored; the IMSI code in the current built-in SIM/ UIM/ USIM card in the process of power-on of a mobile terminal is read and compared with the IMSI code in the matched SIM/ UIM/ USIM card, and according to different comparison results, the mobile terminal enters a lock state or modifies the IMSI code corresponding to the matched SIM/ UIM/ USIM card and further sends the information of the mobile terminal and the current SIM/ UIM/ USIM card under the lock state. The method of the invention can lock the terminal when the mobile terminal is stolen and send the information of a person suffering theft to a real user, thus ensuring that the stolen mobile phone is possible to be returned to the real user.
