Abstract

The invention provides a method and device for permanent remote closing of a SIM card. The method for the permanent remote closing of the SIM card comprises the following steps: a server acquires a permanent remote closing request; the server sends a permanent remote closing command to a first terminal; the first terminal generates a personal identification number (PIN) code, validates the PIN code, and after the PIN code validation is completed, repeats the PIN code generation and validation process until the validation fails for N times, so that the SIM card is locked; and the first terminalgenerates a personal unlock key (PUK) code, validates the PUK code, and after the PUK code validation is completed, repeats the PUK code generation and validation process until the validation fails for M times, so that the SIM card is deadlocked. The method and device for the permanent remote closing of the SIM card provided by the invention has the advantages that the SIM card can be remotely deadlocked, so that user data leakage can be prevented, and high user data safety can be guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to communication engineering technology, and in particular to a method and device for permanently remotely closing a SIM card. Background technique [0002] The subscriber identity module (Subscriber Identity Module, referred to as SIM card) is used for the user's identification, and stores the terminal user's information, the encrypted key, the terminal user's phone book, photos and other contents. [0003] When the terminal is lost, in order to ensure that the data of the terminal user stored on the terminal is not leaked, the SIN card needs to be locked. If the terminal user has set the PIN code of the SIM card on the terminal, then the holder of the existing terminal needs to enter the personal identification code (Personal Identification Number, PIN code for short) of the SIM card when turning on the terminal. After entering the SIM card code, the SIM card will be locked. At this time, the terminal ...
