How to Silence Unknown Callers on iPhone

In this post, we’ll see how to silence unknown callers on iPhone. In this instance, I’m using iPhone X (iOS 13.1.3). Let’s get started.


  1. Open Settings.
  2. Hit Phone.
  3. Tap the toggle switch beside “Silence Unknown Callers” to enable it. Remember that the “Green” means enabled.

That’s it. From now on, when you get a call from a phone number which is not in the recent outgoing calls, Contacts, Mail, or Messages app, then it’ll go straight to the voicemail and shown in the Recents list.
