As of today 8/25/14 at 8:56pm Indiana time I turned both of my phones cellular data off. I was being charged data during times I was connected to wifi. The only time I am not on wifi is when I am driving so I'm not using any data. I have an iphone 5. Anyone else having this same problem? We have never used close to our data max and today we have reached 75% and have 8 days left on our cycle. Something is not right.
