I got the same text from 36245. You cannot reply to the text. I live in the Nashville area and have never heard of Bank Tennessee. Its a scam. I tried to call the number back to [***] with them but I got a fast busy signal.
I did a reverse lookup on whitepages.com and this is a unlisted landline in Memphis. Ought to report them to AT&T, but it might not even be the real sender.
Bank Tennesee is real bank in Memphis, TN with several branches.
I saw this on their website by following a "Important Security Information" link. http://www.banktennessee.com/index.asp?page=5074
BankTennessee has received numerous reports from customers as well as non-customers about phishing schemes this week. Thieves are sending emails and text messages that appear to be from us. As part of the scam, unsuspecting persons are redirected to a phony website or to call a phone number that may look or sound exactly like the real thing. While these schemes change frequently, they usually ask you to call a particular phone number or go to a website immediately and then ask you to provide personal data. If you provide the requested information, you may find yourself the victim of identity theft."
