Specifically, in the setting of the mobile terminal, a security contact may be set in advance. After the setting is complete, you need to bind with the security contact to complete the relevant security interaction.

When the mobile terminal is stolen or lost, the user can send a short message to the mobile terminal through the pre-bound security contact. At this time, the mobile terminal will judge and analyze whether the short message contains instructions for controlling the terminal to block radio frequency. If there is an instruction for controlling the terminal to perform radio frequency blocking, step S102 is executed.
