Hey, I am very happy I was able to KEEP unlimited data on two phones when I upgraded last friday. The wife and I went in to get new gs3 and thought we were going to loose the unlimited data plan. Turns out the guy helping us said we could keep unlimited if we got another line and swap. Im not sure how he did it, but something like this.. I give my upgrade to the new line then give the new phone to my number. Did the same with the wifes phone. Basically he said I was kinda providing the phone and could keep the data. So we end up paying 10$ more a month and have a third line we wont us.. anyone have this luck?
