A:AnswerThis TV comes will a full tuner to receive local channels. You will need a high definition tv antenna and, of course, be near enough to the station to receive their broadcast (like over-the-air TV has always been).
For streaming local stations, it entirely depends on the streaming service you use, but you will always pay a fairly high premium to get local stations.

A:AnswerHi, Keke.
While this and all our Fire TV Edition TVs can, in fact, connect to a mobile hot spot, we always recommend to have a steady strong network, since hot spots are not 100% reliable to provide the amount of internet these TVs tend to use.

A:AnswerSpotify, Amazon music, and Pandora are available. You can also download SiriusXM, Tidal, and VEVO. I sometimes use YouTube for music and Audible for books.
A:AnswerNo. The TV is a smart tv with Amazon Fire. No Fire Stick needed, just plug the TV in and go... well, you will have to sign into your amazon account.
