I don't have broadband/wifi connection where I live and rely on 3G for facebook/browsing etc. I don't rely on it too heavily, however have racked my brain trying to figure out why I'm using so much, compared to the same usage I was using with my 4S on iOS5, with no issues.
In the first day of having my iPhone 5, I used over 1gb of data and I had barely even used the phone!
I've googled it and people overseas seem to be having the same issues but no real explanation as to why it is using so much! Tired of having to fight the charges on these high bills as I know I'm not (intentionally) using the amount of data I'm being charged for.
Anyone else having the same/similar issues? Any fixes?
