A mobile communications device comprises a transceiver 2 for wireless communication with a telecommunications network, a microprocessor 1 for controlling said communications device, and a power source 4. Means are provided for registering the handset with the network, and requesting transmission to the device of data stored in a service provider, and further means to implement these processes periodically. The communications device may have a stand-by state, wherein said device may receive signalling from said network and a polling state, in which state said device may register with said network. It is preferable that said standby state requires substantially more power than the polling state. |
