We had Kat's experience although we didn't catch the word Texas. The message was superimposed over a Spanish language marketing call from AT&T. Same exact phone number: *721 773-370-7991. Reverse lookup shows that (773) 370-7991 is an unlisted cell phone number in Chicago. Feels a bit like a scam to us.
