Abstract

The embodiment of invention provides a mobile terminal card locking method and device and a mobile terminal. The method comprises the steps of determining whether a card locking directive is received or not, if the answer is affirmative, calling a security interface of the security switch service to lock a user identification module SIM card of the current mobile terminal; if the security service monitors that the SIM card is replaced with a new SIM card, prohibiting the current mobile terminal system to use the new SIM card. The method solves the problem that after the mobile terminal is stolen, it is unable to prevent the mobile terminal from being used normally by a thief through replacing the SIM card. The advantage that the use of other SIM cards is prohibited to reduce the incidence rate of the mobile terminal stealing cases can be achieved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a card locking method and device for a mobile terminal and a mobile terminal. Background technique [0002] With the widespread use of mobile terminals, the theft of mobile terminals occurs more frequently. After the mobile terminal is stolen, information such as user data on the mobile terminal may be used by lawbreakers, thereby causing personal and property losses of the user. Therefore, the anti-theft of mobile terminals is more and more important. [0003] In the prior art, the main steps of an anti-theft method for a mobile terminal include: first, the user of the stolen mobile terminal sends a short message in a specified format to the stolen mobile terminal through a mobile terminal; then, when the stolen mobile terminal receives the When sending a short message, parse the short message; finally, when the number corresponding to the mobile terminal that...
