I received a "Message to 5072157116 failed: Denied." text message on my phone this morning while I was getting ready for work. Thing is, I didn't send a text message and I don't know anyone in Pipestone. Not sure what this is all about.. but I deleted the text and didn't call the number after googling it and finding this page!
The scam is 2 fold. (1) Get you curious (2) Call the number back. What is worth as much as money to a criminal? Something that is worth money. Your working phone number. Which can be sold to other scammers. Part 2 of this scam is many of these 1 ring calls are from Caribbean countries. You call - International rates apply - scammer gets a cut. Pretty simple, right?
