WhatsApp data calls have become extremely popular, with many people relying on them for daily communication. However, along with convenience, these calls also bring certain problems. In an era of rising cyber fraud, receiving WhatsApp calls from unknown numbers has increasingly become a cause for discomfort.

If someone has your phone number and that number is linked to WhatsApp, calls can be made easily. As a result, many users receive frequent calls from unknown numbers. To address this issue, WhatsApp offers a privacy setting that allows users to silence calls from unknown callers.

Why should you silence unknown WhatsApp callers?

Stopping WhatsApp calls from unknown numbers can significantly reduce annoyance. Spam calls and potential fraud attempts can be largely prevented. Numbers will still remain in the WhatsApp call history, allowing them to be checked later if needed. Only calls from known contacts will come through, which also improves security.

However, it should be noted that when this option is enabled, the phone will not ring when an unknown number calls. The number will still appear in the WhatsApp call log. If you later call or message that unknown number, it will no longer be silenced automatically. In such cases, if you want to stop further calls or messages, the number must be blocked manually.
