PURPOSE: A device for remotely changing a function of a cellular phone and a controlling method therefor are provided to insert a signal for directing to change a specific function into a specific index item, and to transmit the index item to a cellular phone such that the cellular phone can retrieve the index item to execute a set function, thereby remotely changing the function without visiting a specific service area. CONSTITUTION: A function change message generation server(2) inserts a signal for requesting function settings to be changed into a specific index item in SMI format type within an LMS(Long Message Service) message, and outputs the specific index item to a mobile communication network device(1). Cellular phones(3A-3N) retrieve contents of the LMS message wirelessly received via the mobile communication network device(1), analyze whether the specific index item written in the SMI format type exists, and reboot by changing a specific function according to analyzed results, and process data or traffic signals.
