Got same message and called it from work (our number is automatically blocked to outside calls). Asked to enter card #. Stated it was "an automated system and I would not talk to a live person." I did not enter my credit card number. Just know this is a huge scam and if they even get 5 of every 100 texts sent out, they are making a killing in identity fraud. It's a shame.
I'm a t-mobile customer too, but I don't think this is anything to do with t-mobile. They merely delivered a text message.
whitepages.com reverse lookup indicates that this number is a landline located in Campbell County, KY.
I called the FBI and was informed that credit card fraud is investigated by the Secret Service. I would encourage anyone who receives this text to notify their local Secret Service office so we can get this guy behind bars where he belongs.
I too am with T-MOBILE and received this same text. Called the number on back of my card. Do not reply to this and if by chance you fell for it please by all means call your credit card company and report it.
