Something seems amiss here.... Got an iPhone 6 on EE (2GB / 2000 / Unlimited) and since getting it the EE app reckons I've used 1.2 gig already (since Friday), but I've been on Wifi and certainly not done anything of consequence, no video streaming etc...
At that rate even if I go up to 4GB which was the top one on offer its going to last about a week without really doing anything :/
I'm having the exact same issues, the EE app seems to think I have used near on 2GB in a day... I'm so confused.
