How to silence unknown callers

Anyone who has your phone number can call you on WhatsApp. An unknown caller might be someone you haven’t contacted before or saved as a contact. You can block a phone number or silence calls from unknown callers by changing your privacy settings.
Silencing calls from unknown callers means you can focus on conversations that matter to you, while preserving your privacy and preventing unwanted contact.
