Data usage

O2 has just advised me I have used 80% of my monthly data allowance. As I only usualy use about 20% a month, what am I doing differently?

Check in your phone settings where your data is being used @Anneton47

So many posts about excessive data use? Weird really, as being stuck at home means I'm always using Wifi.
