Turn on Silence Unknown Callers
The iPhone has a feature called Silence Unknown Callers, which you can pretty much guess what it does, but it’s much more than that. When Silence Unknown Callers is on, it’ll automatically block phone numbers that you’ve never been in contact with or that you don’t have saved in your contacts list.
What’s cool about this feature is it’s pretty smart. If someone has shared their phone number in an email, or you’ve texted with that person before, the phone call will still go through, which is great if you don’t have every person you talked to saved in your contacts.
The only requirement to enable Silence Unknown Callers is that you have at least iOS 13 installed on your iPhone. Afterward, you just need to follow these steps:
- Go to the Settings app.
- Scroll down and tap on Phone.
- Scroll down again and select Silence Unknown Callers.
- Toggle Silence Unknown Callers on.
Before you enable this feature, make sure you save all the important contacts from people you do want to get phone calls from.
After you enable this feature, phone calls from unknown callers will go directly to voice mail. You’ll still be able to see the phone call in your recent calls list, and you’ll still get voice mails.
Also, it’s worth noting that if you place an emergency call, Silence Unknown Callers will be automatically disabled for the next 24 hours so people can reach you during an emergency.
