A wireless communication unit ( 200 ) and corresponding method ( 500 ) selectively routes calls originated in one wireless communication network ( 105 ) through another wireless communication network ( 104, 108, 110 ). The communication unit comprises a transceiver ( 203 ) suitable to support an air interface with a first wireless communication network and with a second wireless communication network; a user interface ( 211 ) operable to initiate a call to a number of a target unit; and a controller ( 209 ), coupled to the transceiver and the user interface, and operable, responsive to the call initiation and when the wireless communication unit is operating in the second wireless communication network, to selectively hairpin the call through the first communication network.
