Abstract
A mobile communication device is adapted to provide voice communications with use of a voice service and data communications with use of a data service. The mobile device maintains a preferred network list as well as a service access list in its memory. The preferred network list has a listing of a plurality of networks with assigned priorities for network selection. The service access list has a listing of a plurality of networks that make the data service available to the mobile device. The mobile device performs a scanning operation for identifying one or more communication networks available in a coverage area of the mobile device. When a home network of the mobile device is unavailable in the coverage area, the mobile device consults the preferred network list and the service access list for identifying one of the networks identified by the scanning operation. The mobile device attempts to register for the data service via the identified network and, if successful, operates its wireless transceiver with the identified network to use the data service. If the attempt to register for the data service fails, the mobile device excludes the identified network from being listed in th…
