An extra $20 to tether/hotspot? F-you. It's none of your business how or when I use my device. You're providing a dummy pipe connection to the internet. It's almost an invasion of privacy trying to tell us how we can use our internet that we're already paying for. Next thing you're gonna tell me is I have to pay an extra fee to use it when in bed.
How is it an invasion of privacy. Every single other carrier charges for tethering and yet when AT&T does they are the bad guy. I'm glad they are charging for it because if your are consuming more than you should pay more.
