A Charging unit for a cellular telephone is provided with having means for connection to an electrical power source and a charging circuit for delivering a charging current to a battery pack or the cellular telephone itself, if the cellular telephone includes an internal energy retaining mechanism (e.g., charge storage device such as a battery). The charging unit further includes a plurality of electrical contacts in electrical communication with the charging circuit. Finally, the invention includes at least one user-selectable switch and at least one electrical contact in electrical communication with the at least one user-selectable switch. In accordance with another aspect of the invention, a cellular telephone is provided, wherein the telephone includes a sensing circuit configured to detect the presence of a charging unit. It further includes a circuit configured to identify from the charging unit a designated number to which to forward incoming calls to. Specifically, once the telephone senses that it has been placed on a charging unit, it then looks to the circuit configured to identify a designated number to forward calls to. Preferably, this is accomplished by one or more inputs provided from a user-selectable switch on the charging unit. Finally, the telephone includes a number identifying circuit electrically connected to the at least one input and configured to identify a designated number to transmit to a cell site as a call-forward number. This may be accomplished, for example, by a CPU accessing a number storage memory.
