发明名称 Mobile communication terminal and method for managing use-history information
摘要 Disclosed is a mobile communication terminal having a subscriber identity module (SIM) card. The mobile communication terminal includes a memory unit for storing use-history information of the SIM card inserted into the mobile communication terminal according to a subscriber identity number of the inserted SIM card, and a controller for determining the subscriber identity number of the inserted SIM card, determining whether a predetermined storage area corresponding to the subscriber identity number exists in the memory unit, and generating the predetermined storage area in the memory unit when the predetermined storage area does not exist in the memory unit. Further, it is possible to search the use-history information stored in a storage area corresponding to the subscriber identity number of each SIM card carried by a user. Therefore, the security for the use-history information of the SIM card can be ensured.
