Upgraded to a smartphone Samsung Nexus. First Data plan and all. So, what is costing me alot of data when I am at work,home asleep,connected to wifi at home(Xfinity). I am barely on the thing and in three weeks 75% of 1GB is already used. I am not a gamer either. So, any explanation of exactly what data charges are for and help would be greatly appreciated. I am thinking about going back to my old phone and my old plan not this new stuff and share everything plan. Thank you
