Disclosed is a system and method to route a call from a roaming UE on a 5G network. The system receives from a UE belonging to a home network an indication of a call to a dialed number. The call requires information associated with the UE that is not available to the first wireless telecommunication network, because the UE is roaming on a visitor network. The indication of the call includes a unique identifier of the visitor network. The system can determine based on the unique identifier that the UE is roaming and send a request to the visitor network to provide instructions on how to route the received call. Upon obtaining the instructions on how to route the received call, the system routes the received call.
