Also got the message today around 1130am, "This is Security National Bank, your card has been deactivated, please call the security department at (418) 615-3159 to reactivate your card, note (either) 418153159", or "1816153159", I couldn't catch what the message was saying. I have AT&T too. Look up the phone number and it's a definately a scam.

Got a call about 40 mn ago on AT&T home phone.  Supposed problems with (nonexistent) card at Financial Center Credit Union.

Has someone called AT&T about this? If they are sending text msg then ultimately the recipient is incurring charges by either paying for the msg becuase they dont have a txt plan or it takes away from the available txt msg's.

hello everybody, i am a cust care agent from att. when you call the number it is a international toll attached. att is working on getting these scum bags out of business.

"This is Finance Center Federal Credit Union. Your card has been deactivated. To reactivate your card, call (418) 615-3159 and note number..." Fraud!

I got one late last week as well.  I have Verizon so this is not AT&T related. I did not receive a text message but the voicemail was pretty much exactly as you said.  It says the mailbox is full and cannot accept new messages at this time when you call them back.  Annoying.  I was heading out for a trip and certainly didn't need problems with my card.
