I have been getting excessve data usage for the past 5 months and its been worse since i have the iphone 6. I always averaged under 1G with my iphone 4S and within the last 4 months of having my 4S and the first month of my 6, my data has been averaging 2G. I haven't used my phone differently and don't know if this is because I switched from an unlimited plan to a 2G plan. Please help!
