A user equipment (UE) may receive a message from the wireless network indicating at least one public land mobile network (PLMN) that provides emergency services support for devices in limited service. The UE may store, in a non-volatile memory (NVM), an identifier of the at least one PLMN in a whitelist of limited service emergency services support. In response to a trigger in a roaming limited service condition of the UE, the UE may establish an emergency session with a selected PLMN based on the whitelist of limited service emergency services support."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods to indicate emergency services support for roaming users","description":"Emergency services support is indicated to roaming devices in a wireless network.
