And no, it isn't an annoyance to me but to my friends.

New Years eve/day I sent a gazillion messages and two of them were listed as failed - or something to that effect.

The next day my friend tells me that I sent the same message "Happy news day" a dozen times, and that she turned her phone off because of it. My phone still had the message listed as failed.

Has anyone else had a similar experience with a "failed" send message not correcting itself when the message is subsequently sent successfully?
