Abstract: A method for managing personal information is provided that uses a mobile communication system capable of supporting short message service (SMS) and including a plurality of mobile terminals having a Personal Information Management (PIM) function. The method edits and transmits PIM data through a terminal and receives and manages the PIM data. Since a record (PIM data) of a PIM database is transmitted or received as a single entity, it is not necessary to enter the PIM data character by character and to input the text message to the PIM database character by character to transmit the data. Therefore, editing and managing of the PIM data can be done easily and swiftly.
