A:AnswerNothing more than you'd pay if you bought the phone directly from Verizon. I bought my phone outright from Best Buy and only had to pay a $40 activation fee from Verizon. My monthly bill didn't change.
A:AnswerBest Buy offers lower monthly payments on their devices as opposed to Verizon - I always recommend getting your new phone through Best Buy. Verizon will still charge you a $40 activation fee for the new device, but if you call and nicely ask them to remove the charge they will.
