Who called from 8484800158

I have 2 T-mobile accounts and yesterday at 9:48 P.M. central time (on both phones) I got a message saying "You have a pending banking message. Call free 1-848-4800-158 to resolve alert"... I have never heard of the company before...

Received text :

Same story at my end. I got this message on both phones. Any idea what kind of scam it is?

I just called.  I got a computer-generated voice telling me that my credit card account was restricted and that I needed to enter some information to activate the account.  Then it asked for my credit card number.  I hung up at that point.

I'm labeling this a "prank call" since I don't see fraud listed as an option.

Received same text message on 3 of my TMobile numbers.  I wonder if TMobile has their list compromised?
