AT&T Unlimited LTE Hotspot $20 without AT&T phones

This is how well the AT&T Mobley is working for me. I'm helping my daughter move from NYC to Columbus, Ohio. I hook the hotspot up in the UHaul truck so my daughter can be on line while driving down the highway. My wife calls from Florida and says the NEST cams aren't working and she doesn't know how to reset them. I tell her hang on and let me check. So I log into the house from my phone while driving down the road doing 70 mph and sure enough, both NEST cams are up and running!!! Amazing!!!
