All of a sudden every time I try to text one specific contact I get a text from ATT saying something like "enter valid 10 digit number" and the only way texts will go through I if I delete the thread and start a new one, but as soon as I get a reply text from the contact I can't send until I delete the thread again. Anyone know what to do?
