Nobody likes spam calls. Whether it's a government survey, a fraud scheme trying to convince you to give over your personal information, or just wrong numbers, having your phone ring incessantly with no one you want to talk to on the other end is annoying. Luckily for us, iOS 15 lets you silence unknown callers.

When you turn on the Silence Unknown Callers feature, any calls from unknown numbers will automatically go to your voicemail without ringing your iPhone at all. The calls will still show up in your recent calls tab in the Phone app, so you can still see what numbers have called you and then choose to call them back. With the feature on, incoming calls will still ring from people in your contacts, recent outgoing calls, and also Siri Suggestions.

If you like the idea of turning your best iPhone into a more effective communication device that doesn't waste your time by alerting you to spam calls, you can turn on the feature by following these steps. Here's how to silence unknown callers on your iPhone.

That's it. Now unknown callers will go straight to voicemail, and your iPhone won't ring at all. Plus, if you feel like the feature is blocking too many calls and wish to turn it off again, you can do so by following the exact steps listed above. Just ensure the on/off switch is gray.
