If you are in an area where you have a weak signal or no signal at all then messages will go to the sent folder but don't notify you that they were failoed. Then the next time you power cycle your phone any failed messages with the red circle you mentioned will then attempt to resend. Even if it's 2 weeks later when you finaly turn your phone off and back on! This caused me some grief a while back, now I always check my service indicator bars before I send any messages :)
