How iOS 13’s “Silence Unknown Callers” Will Stop Phone Spam

Unknown silent callers switch to the Settings app

iOS 13 has a new feature that could avoid you from all the spam and automated calls. The new silencing feature for unknown callers will cut all calls from a number that is not in your contact list.

Stop infinite flow of spam calls

Silence Unknown Callers is a simple toggle that automatically prevents unknown numbers from calling you. Your contacts and the people you interacted with will still be able to call you, but no one's incoming calls will bother you.

This feature is one of the main reasons we are excited for iOS 13 when Apple will release it in the fall of 2019.

How the silence of unknown callers works

The Silence Unknown Callers feature is a pretty blunt instrument: it's a simple switch in settings. Once activated, any call you receive from an unknown number will be disabled. If Siri Intelligence finds the number in the Mail, Messages or Contacts application, the call will be routed.

You can think of it as iOS by automatically pressing the Decline button for you. You will always receive a missed call notification and you will find the number in the Recent list of Phone application.

If you have activated voicemail, the call will be automatically directed to voicemail. This is where the visual voicemail feature will be useful (availability and fees depend on your operator).

When you access the "Voicemail" tab of the Phone application, you will be able to listen to or listen to read the transcript of the voicemail (as you can see in the screen shot below).

If the message is important, you can choose to call it back. Otherwise, delete the voicemail and, if necessary, block the number.

In our tests, we found that if you call back the number, subsequent calls you receive from the number will not be automatically disabled.

How to enable unknown silent callers

This feature is not enabled by default. To enable it after upgrading to iOS 13, open the Settings application and go to the "Phone" section.

Scroll to the bottom of the page and press the button next to "Shut Down Unknown Callers" to activate the feature.

How to make sure you do not miss important calls

What's missing from the functionality of known callers is the nuance and control. If you want to be sure to receive someone's incoming calls, add that person's phone number to your contacts. That's all you can do to control it.

Unlike Do Not Disturb, a call does not succeed after several attempts. When this feature is turned on, your iPhone does not ring even if someone calls you six times in a row.

If you are concerned about missing a major or emergency call from a public phone or hospital, you should not activate this feature.

However, you will still receive voicemails from unknown callers. As long as you check your voicemails, you will not miss anything important.

How to check voicemail for missed calls

Some of these unknown calls may be important and hopefully these important contacts will leave you a voicemail message. You can view voicemails of your missed calls from the phone application.

If you have activated voicemail, open the Phone application and go to the "Voicemail" tab. If you have not activated it yet, you can do it from this screen.

Tap the Voice Mail tab in the Phone application to view voice messages.

You will see the voice messages of the callers at the top. Tap a voice message in the list or select the corresponding "i" button to expand the voice message.

Press the I button next to the voicemail to view the transcript.

Press the "Play" button to listen to the message. If the Visual Voicemail feature is turned on, an excerpt of the transcribed text appears under the number. Tap the box to expand the text.

Alternatives to silence unknown callers

If silently blocking most phone numbers in the world seems too aggressive, there are several ways to disable unsolicited calls.

Although it's not exactly the same thing, you can configure the Do not disturb function (NPD) only to allow calls from favorites. DND also has an option to allow repeat calls. This means that a second call of the same number within three minutes will not be disabled.

You can also use a spam blocker app like Hiya Automatically block spam and automated calls, but it's not a complete solution. The success rate of the application will depend on its database of spam calls, which is never completely complete. Even though it does not block all spam calls, it should receive most.
