Abstract: Techniques to recover from authentication failure are disclosed. During authentication of a user equipment (UE) with a public land mobile network (PLMN), the UE may receive an AUTHENTICATION REJECT with an extensible authentication protocol (EAP)-failure message.

If one is found, the UE can register with the found PLMN.
