Abstract
A device may receive a request for domain name system (DNS) information to be provided to a user device communicating via a visited network. The device may identify roaming policy information associated with the user device and, based on the roaming policy information, may determine that the user device is restricted from sending or receiving data via the visited network. The device may determine DNS information, to be provided to the user device, that includes information that identifies a restricted DNS server to which the user device is to be directed. The device may provide the DNS information to the user device to cause the user device to be directed to the restricted DNS server. The user device may be directed to the restricted DNS server to permit a user of the user device to authorize the user device to send or receive data via the visited network.
