User equipment (UE), and access point (AP) of an unsecured network and method of providing a quasi-orthogonal multiple access (QOMA) resources are generally described. The UE may determine whether it is roaming and if not connect to a home public land mobile network (HPLMN) Enhanced Packet Data Gateway (ePDG). The UE, when roaming, may retrieve ePDG selection information indicating to which of the HePDG and a visited public land mobile network (VPLMN) ePDG (VePDG) to attempt to connect, and connect to whichever of the HePDG and the VePDG is indicated by the ePDG selection information. The UE, when roaming and cannot connect to any PLMN, may extract from the ePDG selection information a default fully qualified domain name (FQDN) corresponding to a particular PLMN and connect to the ePDG corresponding to the particular PLMN through the AP based on the default FQDN.
