To enlarge the possible applications of a car telephone, its control unit can be turned-off. The wireless telephone is blocked for outgoing calls, but is on standby for incoming calls so data arriving during calls can be stored in a memory. The operator can at any time query these stored data. The operator can block undesired callers against reception. Furthermore, he can program the car telephone, for example, in such a way that it sends requests at prescribed times to prescribed communication services, in order to receive data from these, which likewise are stored in the memory.
