I've recently moved over to EE after being with O2 for 15+ years. My last contract with O2 I had 2GB data and never went over apart from the rare occasion where I was out for the office for a week or two. I have WIFI at home and the office so I generally don't use too much data.
I signed up to 4GB with EE, which ran out in no time, I bolted on another 2gb and again its run out with still a week until my data re sets. I'm not doing anything differently, I'm not steaming or watching anything on my way to work as I drive in. Like I said I have wifi at home and the office (connected at my parents and my wives parents when we are there too), so I have no idea where this huge jump in data usage comes from.
Anyone had anything similar?
