- Block unknown account messages: On (This will block messages from unknown accounts only when they exceed a high volume, though WhatsApp doesn't specify the exact threshold.)
- Protect IP address in calls: On (Call quality will be reduced, but it'll prevent your location from being exposed through your IP address to the other person on the call.)
