Can I get a iPhone 5s without changing my plan? (Details Below)?

I currently am on a family plan of 4 people total with Verizon where 4 of us all have iPhone 4's. I want to get the iPhone 5S, but I don't want to change my plan? Can I get the 5S without changing my plan? Also what other fee's will I have to pay if I do get it?

Yeah, but there's a catch. Big Red has a hustle and here's how it works… When you upgrade a phone and want it at the cheap price, you have to ink a new deal, thus busting your old plan. Only two ways you have around it are buy a 5s and pay FULL price or a used Verizon one on Amazon, then just activate it at home using iTunes. You'll need a new sim card since the 4s's won't fit a 5s. Sims can be had from the store for free or cheap to customers. Activate at home and you'll have no extra fees. All of them are getting this way these days. Cell companies don't make friends, they make money. If you don't want to muck up that plan then you better start asking Santa to haul in a little extra coin next month. Best luck.
