Employing multiple mobile devices with varying functional capabilities

Communications over a network are selectively routed to one of multiple mobile devices identified by the same mobile device number. In one example, a method includes identifying a first mobile phone associated with a first activation priority by a phone number and identifying a second mobile phone associated with a second activation priority by the same phone number. The activation priority indicates a priority with which the first and the second mobile phones are activated for communications on a network. Communications associated with the phone number are selectively routed to one of the first mobile phone or the second mobile phone having a highest activation priority. The phone number defines an address at which the communications are routed to the one of the first mobile phone or the second mobile phone having the highest activation priority without being routed to an intervening address defined by another device number.
