A wireless communications device includes a location-dependent alarm which a user can set to be triggered at a target location. A GPS receiver embedded in the wireless device provides position data representative of the current location. When the current location matches the target location, the alarm is triggered. This enables the user to set the alarm to wake him upon arrival at a particular location, e.g. a specific station on a commuter train. In another example, the wireless device can wake the user at one time of morning if the user is sleeping in one location and at a second time if the user is sleeping in a second location.
