My 2 cents on this.
When I signed up online for my phone, I did not see an option for tethering, nor do I see one when I go into MyVerizon. So basically when I signed up for my contract, it was a bunch of minutes and the 30 dollar unlimited data option.
However, (somebody comment on this), doesn't adding a tethering option for 20 or 30 dollars automatically without our consent negate our contracts, due to materially adverse effect or some other technical reason? And if thats the case, then we should be able to cancel our service without ETF. I have not used the mobile hotspot option, even though its free, because I don't want it to be added to my plan later. Either way, I was not told that I would have to call to remove the tethering package. Infact, what I read on another forum, is that we may get a call or text asking us if we want to add it or not, in which case I will say no.
Either way, I'll wait for my bill after the 15th and see what happens.
