No Caller ID vs Unknown Caller

Understanding the difference between "No Caller ID" and "Unknown Caller" is straightforward. While both terms relate to incoming calls without visible caller information, they have subtle distinctions. "No Caller ID" typically means the caller has deliberately blocked their number from being displayed, using phone settings to prevent identification. "Unknown Caller" often suggests the call originates from a source where caller details are not automatically transmitted, such as certain international or cellular networks. Both scenarios prevent you from immediately recognizing who is attempting to contact you, potentially raising curiosity or caution about the caller's identity.
