How To Block No Caller ID Calls On An iPhone

There are in-built iPhone features that allow you to block unknown calls. Here is the guide to blocking no caller ID on an iPhone. Have a look.

The best way to block no caller ID calls on an iPhone is to silence unknown caller features. This feature is available on iOS 13 and above and supported on iPhone 10, iPhone 11, and above versions. This feature will silence calls whenever you get unknown calls.

Your cell phone won't ring if you activate “silence unknown caller.” Instead, those calls will be restricted to voicemail that you can see later. In an emergency, the person calling you can leave a voicemail. Although you won't receive a call, you can see those numbers on the call log.
