A roaming platform is disclosed herein. The roaming platform may receive, via a first communication protocol, an authentication request associated with a user equipment (UE), wherein the UE is subscribed to communicate via a first radio access technology of a home network, and wherein the authentication request is associated with enabling the UE to communicate via a visitor network that utilizes a second radio access technology. The roaming platform may identify an identifier associated with the UE in the authentication request. The roaming platform may determine, based on the identifier, a serving component of the home network that is configured to serve the UE. The roaming platform may obtain, from the serving component, authentication information associated with the UE, wherein the authentication information is obtained via a second communication protocol. The roaming platform may provide, based on the authentication information, an authentication response to the authentication request.
