How to Stop Unknown Calls on iPhone: Easy Steps to Silence Spam

October 9, 2025 By Matthew Burleigh

How to Stop Unknown Calls on iPhone

Tired of getting calls from unknown numbers on your iPhone? You can easily stop them by using features already built into your phone. By activating a few settings, you can block or silence these pesky calls. This guide will walk you through the process step-by-step, showing you how to regain control over your incoming calls and ensure you’re only disturbed by the calls that matter.

How to Stop Unknown Calls on iPhone

In this section, you’ll learn how to stop those annoying unknown calls using your iPhone’s settings. By following these steps, you can filter out unwanted calls and enjoy a more peaceful phone experience.

Step 1: Open Settings

Find and tap the "Settings" app on your iPhone’s home screen.

The "Settings" app is where you control your iPhone’s functions, so opening it is the first step in managing your call preferences.

Step 2: Go to Phone

Scroll down and tap "Phone" in the menu.

The "Phone" section contains all the settings related to your calling features, making it the perfect place to modify how incoming calls are handled.

Step 3: Tap Silence Unknown Callers

In the Phone settings, find and tap on "Silence Unknown Callers."

This option will prevent calls from numbers not in your contacts, recent calls, or Siri Suggestions from ringing your phone. Instead, they’ll be sent to voicemail.

Step 4: Toggle the Switch

Turn on the "Silence Unknown Callers" switch by tapping it.

Once activated, this feature will ensure that unknown callers are silenced, preventing interruptions from unfamiliar numbers.

Step 5: Check Your Contacts

Make sure your important contacts are saved in your phone.

Since only calls from saved contacts will ring through, ensuring your contacts are up-to-date will help you receive important calls without any issues.

After completing these steps, unknown calls will be silenced and sent to voicemail, allowing you to listen and decide if they’re important. Your phone will no longer ring for these calls, giving you peace of mind.

Tips for Stopping Unknown Calls on iPhone

  • Save Important Contacts: Ensure all essential numbers are saved to avoid missing important calls.
  • Review Voicemail: Regularly check your voicemail to ensure you don’t miss any potentially important messages from unknown numbers.
  • Update iOS: Keep your iPhone updated to make sure you have the latest features and security settings.
  • Use Do Not Disturb: Consider setting up Do Not Disturb with customized exceptions for even more control over incoming calls.
  • Block Specific Numbers: For persistent unknown callers, consider blocking specific numbers through your call history.
