I just got a txt from this number saying I won $1000 from Best Buy and to go to a certain website to claim it. I am really skeptical about it. It's probably some sort of scam or advertisement.
Just to be on the safe side, check your phone bill for unauthorised transactions. Also, read these posts from whocallsme-mine for 447773744001, and DieZel's from 2280477042 (he was robbed of $3000). Some Nigerian scams offer prizes, and use premium-rate SMS so almost everybody who receives the message gets scammed, whether they want to participate or not. This company might be doing the same thing.
