Iphone 5s Data Usage
I am trying to resolve an issue with my husbands phone. He had an Iphone 4 (that was never updated to I.O.S. 6) until a little over a month ago and never had issues with going over data caps. Since he got his Iphone 5s he has been using extreme amounts of data (1gb a day sometimes) and he hasn't changed his usage. He has actually used his phone less than usual in the last month as he spent over a week in a class where he had his phone away. I have had him turning his cellular data off when he isn't using the phone and it's STILL sucking data up. Last night while he was asleep with cell data OFF he got two notifications about the data usage increasing. Can anyone please offer advice as what we need to do in the settings, etc., to stop this data usage! a $400 bill is NOT acceptable.
