Question: In a Disaster Condition scenario, what is a capability of the 3GPP system for a UE with 5G-only national roaming access in a Visited Public Land Mobile Network (VPLMN)?
Option 1: The UE can only obtain 5G connectivity services from its Home PLMN.
Option 2: The UE can obtain 5G or 4G connectivity services from any available PLMN without restrictions.
Option 3: Subject to regulatory requirements, operator's policy, or UE capabilities, the UE can obtain 4G connectivity services from the VPLMN.
Option 4: The UE is restricted to only voice call services from the VPLMN, with no mobile data service availability.
Explanation: In a Disaster Condition, ensuring continuous service availability is crucial. Given the UE has 5G-only national roaming access, the 3GPP system's capability to support obtaining 4G connectivity services from the VPLMN (under specified conditions) provides a fallback option, enhancing service resilience and availability during emergencies.
