A system and method for remotely triggering an audible alarm within a mobile phone is disclosed. A remote user calls the mobile phone and enters a personal identification number (PIN) attached to a remote calling device. The PIN is processed either within the mobile phone or within a central service. The PIN is compared to a pre-stored PIN. A match between the previously stored PIN and the PIN entered by the user produces a signal that triggers an audible alarm within mobile phone to deter theft and assist in recovery of a stolen mobile phone.
