A method of authorising a mobile communications device (10) to access a communications network includes receiving a request to grant the mobile communications device (10) access to the network, the request including a portable memory device identification, a mobile communications devices serial number and network identification number which have all been read off a portable memory device (14) by the reader (16). The request further includes a pin number which has been input into the input module (18) by a user of the mobile communications device (10). The received portable memory device identification, mobile communications devices serial number, network identification number and pin number are compared with a previously stored portable memory device identification, mobile communications devices serial number, network identification number and pin number and if these correspond then the mobile communications device is authorised to access the communications network. The mobile communications device (10) may be given access to the network for a predetermined period of time. |
