SMS-4007
No connection to the mobile operators is available right now
Why it happens
Every connection of the SMS gateway to the mobile operators is down or stopped right now, so the message stays queued. Rabt reconnects and tries again automatically.
What to do
Nothing to do: the message is sent once a connection is back. If it ends up failed, send it again later.
