Just got a call today, I have T-Mobile.... I have read on this site that other numbers that have called like this that it may be some sort of scam. They say that it is not a valid T-Mobile # and that if somebody does call back, not to give the person your private information. T-Mobile as a reputable company would never call and ask somebody for sensitive info over the telephone.
just started getting calls from this number a couple days ago. I dont answer, they dont leave a message. no prob will add to my 'do not receive calls from' list.
