Abstract: A communication device is configured to store one or more aggregator service application modules for use in accessing one or more different aggregator, services. Each aggregator service offers access through a plurality of offered wireless networks identified by a plurality of offered wireless network identifiers. The communication device maintains a prioritized list of profiles which include one or more aggregator service profiles associated with the one or more aggregator services. A scanning operation is performed for identifying one or more available wireless networks in a geographic area of the device, for producing a scan list of one or more available wireless network identifiers corresponding to the one or more available wireless networks. One of the aggregator service profiles is selected from the prioritized list, causing one of the aggregator service application modules corresponding to the selected profile to be invoked.
