Receiving calls from private or unknown numbers can be frustrating and disruptive. Fortunately, there are several effective methods to block these calls on your T-Mobile iPhone.
What Are Private Number Calls?
Private number calls are those where the caller intentionally hides their phone number, making it appear as "Private Number," "Unknown," or "No Caller ID." These calls are often used by telemarketers, scammers, or individuals who prefer to remain anonymous.
