What does ‘No Caller ID on iPhone’ mean?

When you receive calls from a number not saved in your contact list and the caller has intentionally hidden their call ID, it’s known as a No Caller ID call in simple terms. The person receiving the call can see the No Caller ID on the top of the iPhone’s caller interface. Such calls can be really disturbing and can waste your time if not taken care of. iPhone, through its calling system, enables users to silence such callers by ignoring calls: not informing about the call.
