My daughter went on the internet via WiFi in the reception and via a Mac cable in our hotel room. I know she didn't go on the net via her mobile phone. She checked that the WiFi sign was up every time she was on the net.

Still she got an unspeakable mobile phone bill when returning home claiming she'd been on 3G. She is also sure she turned data roaming off.

She's traveled abroad ****loads of times before, using an iPhone 4, and it has never happened before. With her iPhone 5 all sorts of **** seems to happen.
