An apparatus and method for sending an emergent rescue signal using a mobile communication terminal can perform its operation as follows. A rescue requester requests emergent rescue using a mobile communication terminal and an emergent rescue center which received the emergent rescue-requesting checks an approximate position of the rescue requester, and dispatches an emergent rescuer to the position. The emergent rescuer who arrived the approximate position of the rescue requester sends a remote control signal to the mobile communication terminal of the rescue requester so that the mobile communication terminal can send an emergent rescue signal. Then, the mobile communication terminal sends the emergent rescue signal according to the received remote control signal so that the emergent rescuer can rapidly detect an exact location of the rescue requester.
