Anybody else having issues sending repeat text messages to same person? I reply to message from someone that I just texted and I get - Unable to deliver. Please re-send with area code. I know the area code is in the address book for that person and it's showing that person's name & picture so it has to be linked. I tried deleting all texts in the standard texting app, deleting that person's contact info, and retyping the contact information. That didn't seem to work.
