A mobile communication apparatus comprises a first SIM card, an anti-theft control circuit, a transmission control circuit, and a security module. The first SIM card is engaged with the mobile communication apparatus and has corresponding first identification information. The anti-theft control circuit has a SIM-card-detection module and an information management module. The SIM-card-detection module is used for detecting whether the first SIM card is replaced by a second SIM card and generating a corresponding detection result. The information management module is used for storing the corresponding first identification information, predetermined contact information, and a user personal database. The transmission control circuit is used for transmitting data and/or signals. The security module provides a data security class. When the SIM-card-detection module generates the detection result, the transmission control circuit will send a notice signal according to the predetermined contact information, and when the security module receives the detection result, a data security procedure in the security module is enabled to protect the data in the user personal database according to the set data security class. |
