Why Suddenlink Home Security is calling your phone at 3 am!
Summary — +18002999900
Expert Opinion
Most reports point to the call coming from Suddenlink Home Security—a legitimate alarm‑monitoring service that alerts customers when a sensor trips. The timing (often early morning or late night) matches real‑time security alerts, not a sales pitch. Still, scammers sometimes spoof this number, so treat any request for personal or payment info as suspicious. If you have a Suddenlink system, check your app or email for the corresponding alert before calling back. If you don’t have an alarm, let the number go to voicemail and consider blocking it. In short: verify the alert through official channels and never give out credit‑card details over the phone.
