There are easy ways to stop annoying spam calls on your iPhone. Just follow a few simple steps, and you can keep those pesky spam calls away. You don’t need an extra install in most of these methods because iPhones come with several features to deal with spam calls.

You may also find many apps on the App Store that stop spam calls for you. These apps have lots of spam numbers stored in their databases.

Apple has another feature called Call Blocking & Identification that helps you stop spam calls on your iPhone using additional apps. The final screen may look slightly different depending on your carrier and where you’re based.

2. Silence Unknown Callers

Thankfully, Apple comes with an inbuilt feature to deal with unknown numbers. It was introduced in iOS 13. This feature doesn’t cut off calls when your phone is ringing; instead, it just silences them. This way, you won’t be bothered, but you still have the chance to receive the call. When you activate this feature, your iPhone uses Siri to check if the caller is in your Contacts, Messages, Mail, or recent calls. If the number is there, your phone rings normally.

  1. Launch the Settings app from homescreen

  1. Go to and select Register Here

  2. Tap on the Register button

  3. Fill out the form with important details such as your Phone Number and Email Address, then hit Submit

If none of the above methods work, you can manually block numbers that keep spamming you. This stops them from calling you in the future.
