A mobile device may determine an address of a location server to use for location-based services to the mobile device. In one implementation, a mobile device may retrieve a service list that indicates services available to the mobile device and determine whether location-based services are enabled for the mobile device. The mobile device may additionally retrieve, from a file stored as part of a file structure associated with a smart card of the mobile device, a network address of a location server corresponding to the location-based services. The mobile device may connect to the location server to obtain location-based services from the location server.
