There could potentially be a large number of reasons for this, but I haven't seen this referred to here before, but that doesn't mean it has NOT been experienced before.
Have you searched this topic already, on this site?
What tests have you done already?
Is it happening with ALL messages you try to send, both SMS and MMS?
to ALL people in all locations? for how long has this been a problem?
When could you last successfully send a message?
Can you RECEIVE messages?
What tests could you do -- do you have a second device, with the same or a different ROM to test this?
