Hello that is not an incentive to a lot of people. If you have kept your unlimited data plan you have figured out to get new phones. Unless you have the same phone from 4-5 years ago. Who cares that they now give you the device payment option???
That does not negate a permanent $20 bill increase. I'm use to paying for phones I could give a care less about Verizon giving me the option of paying them over 2 years. That is essentially putting me back under contract, I can just pay it off early.
Seriously you have to come back with an argument better than that.
