Receiving calls labeled as "No Caller ID" can be frustrating and intrusive. Fortunately, there are several applications designed to help you block these anonymous calls and safeguard your privacy.
What Are No Caller ID Calls?
"No Caller ID" calls occur when the caller intentionally hides their phone number, making it appear as if the call is coming from an unknown or private source. These calls are often associated with telemarketers, robocallers, or scammers.
How Can I Block No Caller ID Calls?
Blocking "No Caller ID" calls can be achieved through various methods, including built-in phone features and third-party applications.

- Open the Phone app.
