A mobile cellular telephone (100) is disclosed comprising a communications transmitter (103) and receiver (102) arranged for two-way communication with a base station (BS), and a GPS receiver (105, 106) arranged to power up in response to direct interaction between a user and the mobile phone (100) after the telephone has been switched on. In particular, the GPS receiver (105, 106) may be arranged to power up in response to the user making a call to the emergency services. Recognition by the telephone of an emergency call being made may occur when the user enters the emergency call telephone number, or one or more, but not all of the digits of the emergency call telephone number.
