My current Verizon contract is almost up for renewal. Is there any way to get a discounted phone without losing my unlimited data plan?

Title pretty much says it all. The limited data plans won't be a problem for me currently (I don't even use a gig of data per month, currently), but I know that as time goes on it will become a bigger and bigger issue, and I'd rather hang on to my current deal if possible.

Thanks.
