A caller in a mobile vehicle requiring service determines his location such as longitude and latitude and transmits his location and service requirements in numbers; by wireless mobile phone tone signals to a remote directory station containing a data base with the phone numbers, service classifications and locations of service providers in the area of the caller to derive the telephone number of a provider who is conveniently closest to the caller and connects the caller to the communication channel of the selected telephone number or advises the caller of the selected providers telephone number. The database is regularly updated by the addition and deletion of providers subscribing to the service.
