ABSTRACT:
The mobile telephone includes a detector, a timer and an annunciator. The detector transmits a detection signal when the detector detects that the mobile telephone is in a stand-by mode and is located out of a service area. The timer starts measuring a period of time in response to the detection signal. The annunciator makes at least one of sounds and vibration when a period of time measured by the timer reaches a predetermined first period of time.
