On my Samsung Android device, if I press and hold the power switch, I get a menu that allows me to put the phone into Flight mode and some other things. One of the options disables the data connection. That's the one you are looking for. Disabling sync only disables some things but that option disables all cell data connections.
Yeah, but then if he wants to check it manually, he can't do that. And, if he takes it off flight mode, everything will sync again and it would use all his data.
Best thing to do, disable sync (as I suggested) or if you want it to run via wifi only, you can do that option. That is cool, however, things like watsapp and gtalk on those kinds of things then don't work either. Which, because it is supposed to be instant messaging, defeats the purpose if you only get those messages when you're home.
