How to Block No Caller ID Calls on iPhone: Quick and Easy Ways

In case you’ve been receiving calls with a hidden phone number, I will teach you how to block ‘No Caller ID” calls on your iPhone. Read this post and understand the process.

Calls with “No Caller ID” are usually coming from telemarketers, hackers, or spammers who want to obtain your personal information. They have blocked their caller IDs on their end to keep their numbers hidden and therefore, you can’t raise a complaint against them. Hence, there are also other users who want to keep their caller ID hidden for privacy and security purposes.

But if you find these unknown calls annoying, you can get rid of these unwanted callers by simply blocking “No Caller ID” calls on your iPhone device. You can do this by directly contacting your telecom service provider and have them blocked calls from No Caller ID.

Alternatively, you can also do this from your device itself. We have listed two methods to block “No Caller ID” calls on your iPhone. Let us check each method and find out how it works.

Any of these methods should be able to block “No Caller ID” calls on your device once activated. Whichever method you find comfortable using, feel free to refer to this post.
