Mine told me my debit card was on hold and to press a series of numbers to get it back. DO NOT REPLY!!!!!! I don't know how they know I have a mastercard either... scary world in which we live.
I got the same message on Feb 28th, 2012 at 5:39am. My msg read (9171256788) H5BC CRES Alert 792879. Please call 718-3600876. Then it had call back number of 9171256788. Now I know these things are scams of some sort SO I NEVER call or text back--especially from my CELL PHONE. i believe it will open and access your phone to whoever is scammin and calls will be made all over. I think its the Terrorists trying to access phones to call back to their country... that 718 num is def a Newyork, Brooklyn, or Queens number. My advice DO NOT CALL THE NUMBER AND DONT TEXT BACK FROM YOUR PHONE......
