How to Block Unwanted Calls on Your AT&T iPhone: A Comprehensive Guide

Unwanted calls, such as robocalls and telemarketing, can be a significant nuisance for iPhone users on AT&T. Fortunately, there are several effective methods to block these interruptions.

What Built-in Features Does My iPhone Offer to Block Unwanted Calls?

Your iPhone includes a feature called "Silence Unknown Callers," which silences calls from numbers not in your contacts, recent calls, or Siri Suggestions. To activate it:

  1. Open Settings.
  2. Tap Phone.
  3. Select Silence Unknown Callers.
  4. Toggle it to On.

This feature sends unknown calls directly to voicemail, allowing you to review them later. However, it may also silence important calls from unknown numbers. (techradar.com)
