Question: In a 5G roaming scenario, as per 3GPP specifications, how is the decision made regarding whether a service is provided by the Visited Mobile Network or the UE's Home Mobile Network?
Option 1: Based on the type of subscription (prepaid/postpaid) held by the UE.
Option 2: Determined on a service-by-service basis.
Option 3: Dependent on the UE's device capabilities.
Option 4: Always provided by the Visited Mobile Network for roaming UEs.
Explanation: This is correct because, according to the specifications, the decision to provide a service from either the visited network or the home network is made individually for each service, offering flexibility and customization based on the roaming agreements and service types.
