A control device receives information, e.g., network status information and network loading information, from a plurality of service provider networks and device capability information and status information, from a plurality of user equipment (UE) devices. UEs subscribe to multiple service provider networks. In some geographical regions, coverage is provided by more than one network. The control device generates and sends device profile to network mapping information to UEs on an individual UE basis, e.g., for geographic regions, e.g., 3D regions, where multiple networks are available. Device profile to network mapping information sometimes includes criteria, e.g. rules, parameter, limits, etc. An application on the UE uses the received device profile to network mapping information, along with position information, to select a network/profile to use at a given time. Altering the information provided to one or more UEs allows the control device to perform load balancing between networks.
