Called service support because MIFI was acting up, after going to store and getting nowhere.
He was able to remove the charge.
They could not tell me either, what was downloaded, at the store. Said they could to government but not us.
I can only guess. A few people go up road on edge of our property and camp on neighbor's land.
perhaps someone did hack our mifi. I'm moving it from the west window area to somewhere else in the house. I had it there because I figured a clear shot to towers.
When we do gt on to account page perhaps we can figure it out and then maybe not.
