So the missus has inherited an unlocked iPhone. She has an internet allowance through Orange, not sure how much. How do you keep an eye on how much the internet is being used? Does it stay connected all the time to update the weather and news and other apps and all that guff? How do you stop it doing that? Don't want to get whacked with a huge bill. Sorry this is such a gormless question, I'm not exactly up on this stuff. Cheers!
