Does the unlimited plan end after your 2year "contract" unless you renew/get a new phone?I may decide to order this online as long as I can keep my unlimited. What happens if I order it before the deadline to keep unlimited, but after shipping, I don't get down to Verizon to activate it until after the deadline? Also, I will probably want to order it by putting the cost on my next bill, sell my current phone and pay the extra amount with that money, I've done that before. Is that possible online?
