I don't have a smart phone and have never used a cell phone for data transfer, so I don't understand much about this. I am interested in using a cell phone as a hot spot (I am years out of contract, so I am sure AT&T would like to keep me as a customer) so a new phone is almost a given soon. I am really unclear on the "unlimited data" plan you spoke of. Does that really mean unlimited in every sense with no "throttling" after a certain amount? Unlimited in my case meaning Netflix and like services. Thanks in advance.
