My month subscription just began today. This morning, it said I had used up 10% of my data; before I even used my phone. I was connected to wifi all day, apart from one hour of a commute- it remained at 10% used up. I left my phone at all evening when I was out, and came home, and it said I used up 18% of my monthly data. Impossible. This is very fishy, considering I barely used my phone at all today, never mind the data.
