Abstract
A device may identify a first set of radio frequency (RF) spectrum bands supported by a visited public mobile network (VPMN) for a first radio access technology (RAT), and may identify a second set of RF spectrum bands supported by a user device for the first RAT. The device may compare the first set of RF spectrum bands and the second set of RF spectrum bands, and may determine whether the user device and the VPMN support a same RF spectrum band for the first RAT. The user device may be registered to use the first RAT when the user device and the VPMN support the same RF spectrum band for the first RAT, or the user device may be registered to use the second RAT when the user device and the VPMN do not support the same RF spectrum band for the first RAT.
