The best way to block unknown calls is to leverage the call filtering services of your cell service provider. However, you can silence them to at least prevent them from interfering with your day. Unfortunately, you can’t easily block ‘No Caller ID’ calls using the basic features on your iPhone. So, let’s get into the details and review your options for blocking unknown callers. And let’s face it - things get quite frustrating if a spam call comes in right when you’re anticipating a job offer or a call from an important client. You can never be sure whether you’re dealing with a spammer when a call comes in with no caller ID. Alternatively, save a dummy contact named ‘No Caller ID’ and then block it. You can also use the ‘Do No Disturb’ feature or the ‘Silence Unknown Callers’ option to hide the calls as they come in. The best way to block anonymous calls is by using your cell carrier’s call-filtering services.

So, how do you block ‘No Caller ID’ calls on your iPhone? While it’s true that some people keep their caller IDs hidden for privacy and security reasons, in most cases, it’s the fakers. Calls that appear as ‘No Caller ID’ typically come from telemarketers, spammers, or hackers who want to fetch your personal information.
