SMS Notification Failure

What happens when an sms notification fails to send? Does Ignition attempt to resend the notification? If not, is there anything I can do in the pipeline to implement this?

I am also interested in this. We are running in 7.9 and our Airlink failed and required the power be unplugged and replugged. We had no idea that something was wrong, and missed several text messages. Any updates to this?
