Functionality of a mobile device depends on detected speed of the mobile device. Global positioning system (GPS) technology or tower triangulation may be used to estimate the speed of a mobile device. In addition, the geographic location of the mobile device may be estimated. A set of rules regarding when functionality of the mobile device should be limited is accessed and if the mobile device exceeds a threshold speed or is located in a restricted area, selected features of the mobile device are disabled. Incoming calls and outgoing calls may be restricted according to local regulations. Other features such as emergency dialing, hands-free operation of the mobile device, and playing audio files (e.g., MP3 music files) may remain functional regardless of the geographic location or estimated speed of the mobile device. |
