So I am looking to get a Galaxy S4 in the near future. I currently use a droid 3. The droid 3 is 3G and the S4 is 4G. I have unlimited data with my droid 3 and the 3g network on Verizon. So what if I want to:

A) Maintain my Nationwide plan without being forced to move to Share Everything
B) Get unlimited data on the 4G network
C) Purchase a Galaxy S4

Can I just buy one and put it on the Verizon network and poof there's unlimited 4G and Nationwide plan remains intact? Seems like you could to me....Please let me know if this is all possible? I know that taking the subsidy from Verizon will force changes and I do not want to be charged more for less.
