As some of you can remember, during the beta stages of iOS 6 we saw the "Cellular Plus WIFI" option. The purpose of it was to switch the signal on the iPhone from WIFI to Celular depending on the strengh of the signal. That option was removed for the final release of iOS 6. Ever since I moved to the iPhone 5 I have been giving the phone the same data usage I gave my iPhone 4 (messaging, FB, Twitter, the ocassional Youtube video, no streaming at all). With my iPhone 4 I never exceeded the 3 GB data limit, not even close. Now with my iPhone 5, I am nearing 4 GB with 10 days to go...with the same usage. It could be LTE, but I don't think it should make THAT much of a diference on usage. I have heard of some cases where a person exceeds their limit in just a couple of days. My theory is that somehow the "Cellular Plus Wifi" feature is permanently turned on via a glitch or something, while the option to turn it off was removed. Since a lot of people's LTE signals are faster than their WIFI signals (like me) maybe the phone is switching without letting us know and what we think we are doing on WIFI we are actually doing on LTE. What do yo guys think? Is it possible this be the issue?
