It’s annoying when you receive calls from someone who wants to sell you something.
Or to receive incoming calls from people you don’t know.
When you don’t want to be bothered by unknown numbers and you use an iPhone, you can make use of the following feature:
Silence Unknown Callers
When you enable this feature which was introduced with iOS 13, calls from unknown numbers will be silenced, sent to voicemail, and displayed on the Recents list.
Incoming calls will continue to ring from people in your contacts, recent outgoing calls and Siri suggestions.
In other words: when the feature is enabled and you hear the sound of an incoming call, you know someone’s calling who you have spoken with before.
Be careful though…sometimes incoming calls from unknown numbers can be important!
So be mindful when you want to enable this option which you can find in the Phone settings.
