A combination phone and modem interfacing a computer with switching means using a common transmitter/receiver for communicating wirelessly with a base transmitter/receiver. Controls on the keypad of the phone permit the user to conveniently select by depressing the appropriate key for transmitting or receiving voice messages for the phone or digital data for the computer. In one configuration, the phone, transmitter and receiver are in an enclosure separate from the computer and modem. In another configuration, the phone, transmitter, receiver and modem are in an enclosure separate from the computer.
