A method, system and medium are provided for automatically routing an incoming call to one active wireless-telecommunications device of a set of devices associated with a single wireless-telecommunications-network subscriber. A proximity-based relationship is created between a primary device and a nonprimary device. Upon receiving an indication that the primary device is within a threshold proximity of the nonprimary device, a request is communicated to the network to associate a set of user credentials of the primary device and a set of hardware credentials of the primary device with the nonprimary device. The nonprimary device is thereby activated so that it can receive an incoming call. The primary device is deactivated so that the subscriber can only receive an incoming call on one device at a time.
