A radio telecommunication apparatus 1 is provided with a pager receiver 2, cellular radio device 3, and a control portion 4 for controlling the entire apparatus and supplying power to the cellular radio device 3 according to a message received through the radio calling system. When located within an area of a radio calling system, the portable terminal 1 performs location registration to the radio calling system through the cellular system, disconnects power to the cellular radio device 3, and enters the radio calling standby state. When there is an incoming call to the cellular radio device 3, that portable terminal is called through the radio calling system and the power is turned on to the cellular radio device 3. <IMAGE> |
