Don’t want to be bothered by unknown callers or spam calls on your new iPhone? If that is so, then you can make use of the iOS 15 feature called silence unknown callers.

Read on to learn how to access and activate the iOS feature that mutes unknown calls and blocks potential spam calls on the new iPhone 13.

Silence Unknown Callers in iOS 15

As the name implies, this feature works by silencing or muting incoming calls from unknown numbers. 

This Phone app feature was first introduced in iOS 13. You can make use of this feature to avoid getting calls from people you don’t know.

When enabled, this feature will block phone numbers that you have never been saved in your contacts list or in contact with.

In the case where an emergency call is placed, the feature will automatically be disabled for the next 24 hours in order to let your iPhone be reached. After the 24-hour mark, the Silence Unknown Callers feature will reactivate.

To give you some input on how to manage this feature on the iPhone 13 and other iPhones running on the latest iOS version, I’ve mapped out a step-by-step guide as follows.

Easy Steps to Silence Unknown Callers on iPhone 13

The following steps are also applicable when muting incoming calls from unknown numbers on other iPhones running on the iOS 15 or later platform. 

Actual screens and menu options may vary between device models and network service providers so might as well expect some slight differences on the device interface. Nonetheless, the overall procedure is likely relevant.

Feel free to start whenever you’re all set to configure your iPhone.

Step 1: Go to the Home screen and then tap the Settings icon to launch the Settings app.

Step 2: While on the main Settings menu, scroll down and then tap Phone. Built-in features of the iOS 15 Phone app will load up on the next menu.

Step 4: On the following menu, toggle to turn on the Silence Unknown Callers switch.

The gray switch will then turn into green. This denotes that the feature is already activated and therefore all incoming calls from unsaved or unknown numbers will be muted or silenced and straight to the voicemail automatically.

Note: Incoming calls from people in your contacts, Siri suggestions and recent outgoing calls will continue to ring.

Missed some important phone calls when Silence Unknown Callers enabled?

To avoid missing an important call, be sure to save the phone number in your contacts list. 

Calls from unknown numbers that you failed to answer while Silence Unknown Callers is enabled can still be accessible through your voicemail. 

They will also appear in your recent calls list. That said, you can either check your voicemail or recent calls and make a call back if needed.

Should you wish to disable this feature, simply toggle to turn the Silence Unknown Callers switch off again. 

Filter Phone Calls with Third-Party App

To augment spam call detection and filtering, you can also download and install a third-party app from the App Store.

There are actually plenty of apps that are programmed to detect and block spam calls.

Just download and install your preferred app and then set it up on your Phone app. Once the app is set up, it will determine if the phone number is a spam caller. You then can set it to block the phone call automatically or block the number manually on your device.

You can always remove the number from the blocked list by accessing the Blocked Contacts from the Phone, Messages, Mail, or FaceTime app when needed.

And that’s all about muting incoming calls from unknown callers on your iPhone 13.
