A mobile wireless communication device may communicate information to a first network device for enabling authentication, authorization and/or management of accounting for the mobile wireless communication device for use within a first network. A SIM may enable a communication session with a second network based on data sent to the second network related to the authentication, authorization and/or accounting management for use in the first network. The mobile wireless communication device may be handed-off to the second network and/or may establish simultaneous communication sessions with the first network and the second network without communicating authentication, authorization and/or accounting information to the second network. The first and/or second network and/or another network device may comprise and/or share a session control server. The mobile wireless communication device may receive, store and/or modify additional information associated with the authentication, authorization and/or accounting management from the second network device.
