ZTE Mobley with ATT unlimited plan to replace my HughesNet

So you all realize that when used in your vehicle plugged into the OBD port the Mobley can and will upload vehicle data to AT&T?

I opted for a used AT&T Unity MiFi device purchased from eBay for $50. I then activated it on my AT&T plan which has shared data. No chance of big brother watching my driving habits or it being stored away in the cloud. Works at home, in the car, etc.
