Can't send sms

[Stalonage]

I've had mint for about a month and have had absolutely no issues. All of a sudden today whenever I try to send a message to anyone (iPhone/android) I get an immediate

"Free Msg: Unable to send message - Message Blocking is active."

I have no such feature active.

Has anyone had this or a similar experience on any other carrier ?
