I just purchased a Kindle HDX supporting 4G LTE Mobile Data connection. I first purchased the $20 a month prepaid data plan that allowed for 1G per month. Although I keep my mobile network switched OFF except in the absence of WiFi I thought I was using it sparingly I ran through the 1G limit in 2 days (based on Verizon's tracking). However, my kindly reported that I had less than half that amount. I needed a connection so I upped my plan to $30 for 2G per month. No after a short time, and hardly any use whatsoever Verizon reports I have used the entire 2G and have 0 remaining until the plan renews in 10 days. Meanwhile my Kindle reports that I have used only 1.2G since I First signed up for mobile data service. Even though Kindle has a little disclaimer that says there data usage logs may not exactly match that of the carriers, the discrepancy is too big. I feel that I am being ripped off here. As you can see from the image below, I am still way under 2G. This is very unsettling and just the thing that class action lawsuits are based on.
