I have been having the same issues for several months now and cannot get an answer. My 4g LTE route was off for 5 days and still consumed data every 6 hours like clock work. Yesterday I performed a factory reset of the device and it then turned it off at 6:30 pm. When the device was power off, I checked my usage report on line, while on the phone with a Tier 2 tech, and no data usage was reported. I also logged in around 7:15 PM last night and there was no data usage listed for 6:15 PM. Image my surprise when I logged onto my account this morning and find data usage listed for 6:15 PM, 0.05289 GB and at 12:15 AM for 0.01792. I have yet to get an answer as to how the device is using data when it is powered off but my data usage has increased dramatically over the last several months. The answer I have received, too many time to count, is "lets increase your data plan". While this works great for Verizon, all I am doing is spending more money for data and still have not able to use it due to my router eating data. Any help would be appreciated on this issue.
