Abstract
A wireless end-user device has a configurable wireless wide-area network (WWAN) modem capable of connection to both a home WWAN and a roaming WWAN. At a time when Internet service activities are communicated through the roaming WWAN, one or more processors apply a differential traffic control policy list so as to disallow background Internet data service. When the policy is applicable, an application program interface (API) indicates that an Internet data service is unavailable to an application operating in a background mode, even though that service is available to a different application.
