If your current Verizon phone has a Nano (not Micro) sim - I am assuming you are still using Verizon - you can use it easily in a 5x or 6p (or a 6 for that matter). As long as you already have an active account you literally can just swap it in and out i.e. if you end up wanting to stay with Verizon or want to do side-by-side comparisons you can.

That way, as Darkpriest667 points out, you can just try Fi out. The Fi sim kit is free with the service and the service has no contract terms at all. And the 6p is a fantastic phone no matter what you use it on (some people feel the same about the 5x but I would go with the 6p) - it will work on your Verizon account.

If your current phone doesn't have a Nano sim or you let your Verizon account lapse you could be in for some work, because while the 5x and 6p work perfectly fine on Verizon, they haven't "certified" them yet, meaning new activations are a pain in the rear end. This includes swapping a Micro sim for a Nano sim (also, if you go that route, obviously the new sim won't work in your old phone, but as mentioned the new phone is a good idea anyway).
