I received this text as well. I had previously gotten a text from the same place reminding me that my son was overdue for an eye exam. I'm guessing that USA Optical may be a common link.
Got similar TXT on 4/28/15 @ 9:24 am. She wants to show me boobs, not bra. Anyways, they should show their brain if they have any. :) I bet AT&T had a breach...
I didn't get the bra text. My msg said "I saw you on fb".... Haven't been on fb in over 3 years. Got a similar phishing text last week.
You can fwd the text to 7726 and att will block the sender and track them down.
