I've used TracFones to operate my Sync since 2012 without difficulty. However, TracFone notified me that they were up-grading their system to a 4G network and my LG800 needed to be replaced. TracFone sent me a free phone; an LG306G.
It pared with the sync but the phonebook would not up-load. After a modest amount of research I purchased a SAMSUNG GALAXY CENTURA SCH-S738C 4GB for $19.99 and it restored Sync. harmony.
I only use a cell phone in the Ford & I have over 5000 unused minutes and I don't like to give up on technology.
Hope this helps as I doubt I'm was the only frustrated TracFone user.
