Each time a mobile terminal enters a service area of an information providing device and its location is registered by the information providing device, the area code and local code of telephone numbers and addresses associated with the service area are sent from the information providing device to the mobile terminal. Based on the area and local codes of telephone numbers and the addresses, the terminal retrieves the telephone numbers, names and addresses of acquaintances residing within the service area from an address book stored in its RAM and visually displays them with a notification sound. Thus, the user at the terminal can know access information for acquaintances residing within each service area each time the user enters the service area.
