I received a text message from this number stating that I had won a $1000 dollar Best Buy gift card. Obviously a scam. It lead to a suspicious looking website. I believe the never originates in Cinncinnatti Ohio.
I received the same message and looked up "realtimewinner.com" on Google before I actually visited the address, since it looked like a scam to me. Glad I did.
