I'm surprised that no Yorkshire (and GSG) cavers have not yet pointed out that they get "Welcome to France" whenever they get anywhere south of Coventry.Not caving related but regularly, when climbing on Portland, I get a “Welcome to France” message from my service provider…
It's when you get them out to use them the problems start...And phones are useful for taking photos of surveys for navigation underground (cheaper and easier than buying paper copies and laminating them). And the risk of damage isn't that great when they're in a Daren drum/pelicase.

Unfortunately the Pizza company don’t cover that post code !!
(I was using the phone as a camera and got a surprise message through).
