A device may receive a request to access a network service from a user equipment (UE) roaming on a visiting public mobile network (VPMN). The device may receive UE radio frequency (RF) band information that identifies a UE supported set of RF spectrum bands, and may receive VPMN RF band information that identifies a VPMN supported set of RF spectrum bands. The device may determine whether to permit or deny access to the network service based on the UE RF band information and the VPMN RF band information, and may provide an instruction to permit or deny access to the network service based on the UE RF band information and the VPMN RF band information.
