In one example, a wireless Access Point (AP) is configured to provide network connectivity between a User Equipment (UE) and a private wireless network. The wireless AP obtains, from the private wireless network, an indication that the UE is unregistered with the private wireless network. In response to the indication that the UE is unregistered with the private wireless network, the wireless AP provides, to the private wireless network, an indication to initiate an emergency attach procedure with respect to the UE. In response to the indication to initiate the emergency attach procedure, the wireless AP obtains, from the private wireless network, an indication that the UE is authorized to access the private wireless network. In response to the indication that the UE is authorized to access the private wireless network, the wireless AP provides guest access to the private wireless network on behalf of the UE.
