When you receive a call from a “Unknown Caller,” the phone company’s advanced system fails to determine the caller’s number. The caller’s number is hidden so that even the phone network cannot find out. This could happen if the call comes from another country or there is a slight problem with the phone network.

However, not all carriers or devices support this trick, making it a secret that only some phones can whisper. Think of it as a magical act – the number vanishes before your eyes.

So, when you see “No Caller ID,” you’re witnessing a slice of modern communication mystery, where the caller’s identity remains hidden, leaving you to wonder who’s behind the curtain.
