But not Samsung. I just bought a Galaxy S7 and an S7 Edge. Supposedly the FM chip is installed, but Verizon doesn't support it. Not a big deal to me -- both are great phones that do what we want them to do.
What does a cell carrier have to do with supporting an FM chip? It isn't like FM is being transmitted over cell facilities, is it?
I bought a Moto G2 about six months ago over the counter then registered it with T-Mobile and the FM has always worked. AFAIK T-Mobile doesn't care whether your phone has a FM chip or not.
