I have tried the smsc thing and various other combinations of turning options on an off.
I was texting perfectly fine at 9:00 today. I try to send a text at roughly 9:15ish and it's now not working. I keep getting a message not sent error and a red triangle with a "!" in it beside the message.
It's apparently starting to work again, at 10:49.
Any idea what it was? Why it was happening? How to fix it in the future?
