My family and I are going to be getting the iPhone 5's with 4gb of data a month. I would like to get more, but we I don't think we can afford it. There is going to be 4 of us with iPhones and I saw that the average user uses 1-2gb a month.So we may be coming in close of our limit.My question is what uses up data and how can I manage it so we don't use up alot? Also if I am connected to wifi, then will my data be used up? Thanks in advance.
Added (1). Also let's say I'm in my house and I'm connected to wifi and a cell tower and I'm using the internet, since I'm connected to wifi will it use my data?
