ABSTRACT:
A method for preventing an illegal use of a mobile communication terminal includes the steps of: transmitting a short message service (SMS) message to a lost terminal when a user requests a phone-locking service; and analyzing the received SMS message to set a phone-locking state for the lost terminal. When a terminal is lost, an SMS message containing a ciphered string is transmitted to the lost terminal to set a phone-locking or forcefully turn off an LCD power, so that the lost terminal can be prevented from illegally using by a third party or a stranger and user's personal information can be effectively prevented from leaking.
