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.

A call was made early in the morning, allegedly from an alarm company, requesting my credit card number for verification purposes. I provided false numbers, keeping them engaged for 10 minutes until they hung up, which was somewhat amusing as it wasted their time and resources. It's a futile attempt by inept scammers.

A call was received on Saturday night at 6:55 pm, after office hours, with no name given on the message.
The office recieved a call from a security company, the woman on the phone spoke too fast, saying that the electricity in our area might be down, which would affect our security alarm, it was a bit strange, especialy since they called twice in less than 30 minutes, before we even opened

Scam
Suspicion of a scam arises from a security alarm alert supposedly from my former employer, which seems dubious given the number of people that should have been present

Further investigation into this number was prompted after I contacted my service provider, who listened to the voice mail messages and initially could not identify the caller, leading to suspicions of a scam, but it was later discovered to be a legitimate 3rd party service used for monitoring home alarm systems, although the calls and messages were confusing and raised initial concerns.
The call was received on May 14, 2018, at 4:03 AM.
