I am clueless when it comes to phones. I have an Iphone 5 for my daughter and she has downloaded apps since owning it. Suddenly the monthly bill has gone from £35.00 which she has always stayed within to over £106.00. I phoned Vodafone who said it was internet use. My friend said it could be the GPS is on. We checked and it was. Could this be the reason? And do I have any chance of asking VF for a refund or partial refund due to it happening without realisation. So worried as its such an unexpected bill. I do trust my daughter, I think it may be a case of downloading an app that may have taken advantage, so to speak. Please help x
