Re: Text Messages Failing

I am having the same problem here in southern New Hampshire.
I periodically lose the ability to send or receive text messages.
When I dial *777*2# to see how many texts I have left, it says 0, but that can't be correct, because (a) I have an unlimited texting plan, and (b) a few minutes later I can re-send the text.
Any ideas what is happening?

I did send a big report using the AT&T Mark The Spot app :-)
