Default [Q] Can I change Verizon Note 2 APN settings without root or custom ROM?

So I recently stopped getting verizon service due to there bad reliability in my area (I could have 4 bars but not be able to load a webpage or make a call), and i am considering switching to metropcs, since there cheap and have decent reception where I live. I already have a Note 2 from Verizon and I know the SIM slot is unlocked, but I know without metropcs APN settings I cant get data on it. Can I change the APN settings without a root? I am running the stock version of 4.3 if that helps. I know rooting or custom roms can void your warrenty and I have over 6 months left and dont want to lose it.
If you have any idea if this can be done please let me know, thanks
