What does it mean when Iphone says no caller ID?

When you see a call from “No Caller ID” appear on your screen, it means that the person who is calling you has stopped their phone number from being visible to you. This means that they purposely want to hide their contact information from you so that you cannot trace the call back to that person.

What is difference between unknown and no caller ID?

“No Caller ID” means just that – the caller overtly blocked their ID from being displayed. ”Unknown Caller” means a caller ID was provided but not recognized.
