Message Not Sent Notification/Error

[Golfdriver97]

I had this issue a few months ago, and I got rid of it. I can't remember what I did. But now I have the same issue and I can't get that message not sent to come out of my phone and I can't remember what I did but I know I didn't have to have my SIM card deleted or take it to the phone people so if anyone has any ideas please let me know
