Question: In a roaming scenario outside the Home Public Land Mobile Network (HPLMN) country, how is the override category for Calling Line Identification Presentation (CLIP) set in the Visitor Location Register (VLR) if not received from the Home Location Register (HLR)?
Option 1: The override category is set to 'yes' by default to ensure service continuity.
Option 2: The VLR queries an additional database to determine the appropriate override category setting.
Option 3: The override category is set to the default value 'no'.
Option 4: CLIP service is temporarily suspended until the subscriber returns to the HPLMN.
Explanation: In a roaming scenario outside the HPLMN, if the VLR does not receive the override category for CLIP from the HLR, it defaults to a predefined setting to manage the service. Setting the override category to 'no' by default ensures a consistent handling of CLIP requests in the absence of explicit instructions from the HLR, balancing service availability with potential privacy or security concerns.
