Question: How does a UE (User Equipment) apply SIP-based service lists exempt from 3GPP PS Data Off when provisioned with a single list without specific PLMN indications?
Option 1: The single list is only valid for the home PLMN, and an error is reported for VPLMNs.
Option 2: The UE ignores the list until it receives separate lists for home and visited PLMNs.
Option 3: The single list is applicable to both the home PLMN and any VPLMN the UE roams in.
Option 4: The UE uses the list only for roaming in specific VPLMNs, not in the home PLMN.
Explanation: According to the provisioning rules for UEs, when a single list of SIP-based services exempt from 3GPP PS Data Off is configured without specifying the applicable PLMNs, this list defaults to being valid for both the UE's home Public Land Mobile Network (PLMN) and any Visited Public Land Mobile Network (VPLMN) it may roam in. This ensures seamless service continuity across different networks with the provided exemptions.
