That's true. Having experienced very severe service interruptions after Katrina in this area, text messaging was a life saver. Your phone will keep trying to deliver it, and when your phone has a signal, it will put it through. Conversely, when your phone comes onto the grid, the system will deliver the text messages waiting. I think they only stay in the system for 14 days, though.
