Abstract

The invention discloses mobile phone antitheft technology and a mobile phone antitheft method. A mobile phone is bound with a corresponding subscriber identification module (SIM) card by setting a password, and when a new SIM card is inserted, if a correct password is input, the mobile phone can be normally used, and if a wrong password is input, the mobile phone is disused after 24 hours. The mobile phone antitheft technology and the mobile phone antitheft method protect the interest of a mobile phone user, and the information and data of a mobile phone owner cannot be leaked due to the loss of the mobile phone; therefore, the loss is reduced.

Description

technical field [0001] The invention relates to the field of electronic product anti-theft technology, in particular to a mobile phone anti-theft technology and method. Background technique [0002] Generally, before using the mobile phone, the SIM card (Subscriber Identity Module) must be installed before it can be used normally, otherwise it can only make some emergency calls, such as 119, 112 and so on.
