Sorry for the late reply

TracFone seems to like to be difficult often and not just give you a list of phones that work with the BYOP.

So far I have tried a Verizon iPhone 5S (my current daily driver) and an AT&T iPhone 3G (just for fun for a bit).
I'm almost certain most phones will work, but I wouldn't guarantee it.

If you call them (1 (800) 867-7183) and get to a human and ask them "Will phonename work with the BYOP program?" they'll probably be able to tell you. (That's what I did)

I would highly recommend you BYOP instead of using a TracFone. Most are bad, and the others are mediocre at best. I would reccomend you get an iPhone, Galaxy, Moto, LG G, or HTC.
