I bought FP4 three years ago and had a decent run with it until an update happened that made my phone unable to connect to my carrier (no calls or internet :( ). After a lot of back and forth with support they admitted that LTE on my country (Greece) was not officially supported ! They did refund me after that admission so I bear them no ill will. I hope they succeed in their mission and if their phone worked for me, I d still be using it.
