ABSTRACT:
A mobile terminal and a method for protecting information in a mobile terminal, the method includes: sending an information protection command to a mobile terminal via current home mobile switching center of the mobile terminal; the mobile terminal receiving and decoding the command, and executing a protection operation on the information in the mobile terminal according to a protection range defined by the command. When the mobile terminal roams, an information protection command is sent to its current home mobile switching center via a home location register for the mobile terminal. When the mobile terminal is powered off, the command is stored in the home location register, and when the mobile terminal is powered on again and informs the home location register, the home location register sends the command. Thus, information to be protected in a mobile telephone may be deleted or locked via remote operation.
