I had a same problem and now I solved it thanks to your information!
Those guys who have sim detection problem they have to insert an actual nano-sim, because FirePhone is very sensitive in terms of sim. I had sim detection problem. the sim was cut into a nano-sim and had a terrible time with the phone but by changing the sim and inserting a real nano-sim, the phone worked like a charm.
I have one for the past six months i can say all android apps ; waze, IG, facebook, whatsapp work fine side loaded, there are tutorials out there to explain how to install google play store. This phone has great battery life, great display for reading and price is great. the only negative for me is the camera which is poor for a 13mp, its very dark and you cant adjust this before taking shots only after, otherwise a great buy for the price.
