Abstract:
1. A mobile communication apparatus comprising: a first Subscriber Identity Module (SIM) card, comprising a corresponding first international mobile subscriber identity (IMSI) code, being coupled to the mobile communication apparatus; an anti-theft control circuit comprising: a SIM-card-detection module for detecting whether the first SIM card is replaced by a second SIM card comprising a corresponding second IMSI code, and for generating a corresponding detection result if the second IMSI code is compared to be different from the first IMSI code; and a subscriber information management module for storing the corresponding first IMSI code and a predetermined contact information wherein the subscriber information management module comprises a user's personal database; a security module providing a plurality of data security classes for setting, wherein a subscriber needs to input a second security code before setting and/or modifying the data security class, and only after the imputed second security code is confirmed to be correct, the subscriber is allowed to set and/or to modify the data security class of the mobile communication apparatus; and a transmission control circuit for transmitting data and/or signal; wherein when the SIM-card-detection module generates the detection result, the transmission control circuit sends out a notice signal and transmits at least a portion of data in the user's personal database to a designated electronic apparatus according to the predetermined contact information stored in the subscriber information management module.
