Silent calls like this one, where only breathing echoes before the line goes dead, often signal automated probing for active numbers. Surprisingly, these aren't always harmless—scammers use them to verify if your phone is live, paving the way for more targeted harassment later. As a data protection measure, never return such calls; it confirms your line's activity to bots. Enable call blocking on your device for unknown numbers, and register with do-not-call lists to reduce unwanted contacts. If patterns persist, report to telecom authorities to safeguard your privacy and prevent data harvesting.
When I picked up, all I heard was heavy breathing before the line went dead. Creepy, right? 😬
