## Abstract

Examples pertaining to no subscription permanent identifier (SUPI) or no non-3GPP coverage in 5G mobile communications are described. A processor controls a communication device of a UE to connect to one or more wireless networks and receive one or more 5GS services via a 3GPP access and a non-3GPP access. The processor performs either a first procedure or a second procedure. The first procedure involves: (i) detecting either no Subscriber Identity Module (SIM) being inserted in the UE or a SIM inserted in the UE being invalid; and (ii) entering the UE into a 5G no-SUPI substate responsive to the detecting. The second procedure involves: (i) performing registration or determining that the UE is registered to one or more 5GS services over the non-3GPP access; (ii) detecting an absence of non-3GPP coverage; and (iii) entering the UE into a no access point available substate responsive to the detecting.
