It's a rare and exhilarating experience to go without that most basic form of messaging, but I was off the grid completely on a remote shore in Alaska for a week last year. I also cross national borders quite regularly and therefore have contingency plans in case some overzealous/corrupt official decides to separate me from my communication devices. And of course one is not exempt from natural disasters, or the periodic collapse of civilisations.
