How To Block ‘No Caller ID’ Calls on iPhone 12/13 (iOS 15)

Rate this post

It’s frustrating that my iPhone 13 is constantly bombarded by unsolicited calls from people whose numbers are not displayed in the “No Caller ID” list. Sales teams often resort to annoying tactics like cold calling to gain new clients. The iPhone’s operating system, iOS, includes a feature that allows users to prevent calls from being received without a matching Caller ID.

The problem has been fixed in more recent iOS updates, which are now centered on making the user more productive. You should place the safeguards to stop sales calls and telemarketers from reaching you. This tutorial will show you how to use caller ID blocking in iOS 15.

What is the Silence Unknown Callers feature in iOS 15 Devices?

Apple has implemented a new function called “Silence Unknown Callers,” which serves as a virtual “exit door” for harassing callers. To use this function, you must manually enable it on your iPhone. Therefore, familiarity with this process is highly recommended.

Unknown callers will be muted on your iPhone. The question is, how do you interpret that? iPhone will not display any incoming calls from unknown numbers. All calls from the mysterious will be sent to Voicemail.

  1. However, you can find out which unknown number called you earlier in “Recents”.
  2. Open the Phone app and choose “Recents” to find out about it.
  3. The feature won’t bother regular calls coming from saved contacts.

By default, “Silence Unknown Caller” won’t cause any issues, as it will let calls from anyone on your contact list.

You find it annoying because strangers keep calling you while you’re in the middle of important activities like meetings, conferences, trips, etc.

I’ll show you where to find “Silence Unknown Caller” in iOS 15 and how to turn it on.

This method of blocking incoming calls without visible caller ID is recommended for use with the following gadgets:

  • iPhone 6
  • iPhone 7
  • iPhone 8
  • iPhone X
  • iPhone 11
  • iPhone 12
  • iPhone 13
