I don't care what the ToS says. That's the truth. I rarely if ever tether. Most of my data plan is wasted because I spend 90-95% of my time on Wifi, so I am not even getting the data that I am paying for.
I understand that VZW doesn't want me to do it, and I don't care. I worry about this as much as I worry about getting caught jay-walking. Sure, it could happen, but the chances are slim and the consequences minimal. What can they do?
VZW- "We caught you tethering 11mb of data over the past 5 months, your contract is terminated"..
Let's rewrite that...
VZW- "We caught you tethering 11mb of data over the past 5 months, so we need to charge you $20 for each of those months for the data plan. Plus a service charge. Plus late fees for each of those months. So that adds up to $200. You will need to pay it now over the phone. Would you like to do an electronic check, debit card or credit card?"
If you make some claim like you had no idea it wasn't free, or you didn't get a TOS, or the Verizon Sales Rep said you could (because they were uneducated), or you read on the internet somewhere that it was free and you belived that or whatever else claim you want to make to try to avoid paying it, they will probably stop service on your phone until you pay or you can terminate and pay the ETA.
If you're lucky you can put that total amount down a little and make monthly payments (talk nice to the CS). But doubtful.
Since we all know this is about money, they're NOT going to terminate anyone's contract. And they will make you pay.
