So after seeing the $18000 bill man and hearing his tethering problem AFTER the fact that I think I've done this I'm starting to sweat bullets. Yesterday I took a video using my phone and could not get it to load on anything other then youtube. However, it would not download to youtube unless I used wifi so I set it up at home with mine (which is also verizon) for the split second I needed for it to download successfully and then turned it off. My question is whether this will cost me anything or not? We have the $25 data plan or whatever the highest is but last month my mother got an outrageous bill and the people never actually answered it well. I'm seeing in some threads that different things aren't placed under the data plan even though it says unlimited? Like what? This seems ridiculous, if it isn't unlimited is it not illegal to be putting that everywhere? Thank you to anyone who helps me out, I'm starting to have panic attacks.
