Patent number: 7599684Abstract: A method and apparatus for setting terminal information using a Subscriber Identity Module (SIM) include inserting a SIM into a terminal and automatically setting terminal information stored in the SIM. In accordance with preferred embodiments of the present invention, there is no need for a terminal user to set the terminal information again when the terminal user uses different terminals to operate the current terminal according to the terminal information, which was used in the previous terminal and set in the SIM, when operations of the current terminal require the same, such as when the current terminal displays data. Thus, the terminal information that was previously used can be directly set using the SIM.Type: GrantFiled: September 18, 2002Date of Patent: October 6, 2009Assignee: LG Electronics Inc.Inventor: Kwang-Nam Kim
