Text message problems?

I have a data only plan, but I decided to try the Call and Text add-ons. The calling works fine and I can still receive texts, but when I send I first got "error 21" and now after following some of the troubleshooting steps here, I get an "incorrect phone format" error. I have tried all the recommendations (other than let it resolve itself) with no success.

    What number do you have in settings for SMS service centre? It should be +14385200092.
