A system enables a user to communicate with another person via an external device, e.g. an audio, video, display interface. The external device includes a short-range transceiver, a memory, and an output interface. The mobile device includes two network transceivers, typically a cellular transceiver and a short-range transceiver, typically Bluetooth. In operation, the user prepares and stores a list of external devices with assigned IDs. The user further stores a list of phone numbers (phone book information) of contacts on the cellular network associated with the external devices for delivery of messages to the selected external device(s). The mobile device scans the network, and detects messages from associated contact source(s). The messages are stored by the ID. When the mobile device is within the coverage area of the external device, the mobile device transmits the message(s). The external device interprets the message for output to the intended recipient.
