Listen, I know this has been asked many times before. There are probably countless answers to this question all over this forum. I apologize for asking again but I must not have been using the correct search verbage and I am in a position where I need to tether and have answers about what to expect.... In short, if I am doing a lot of data uploads and downloads with MyWi tethering is AT&T going to charge me for it? Do they become aware of the tethering at all? Thank you in advance for your assistance.
