It's two parts you need a provider and an app, some providers provide the app but not the best ones. Don't think we can discuss this much in this sub though.
Iptv is a perfect solution, as mentioned above you need to find a good provider and tivimate is the highest rated app. You shouldn't need a VPN of you have a good provider but sometimes it is necessary.
I use fire stick for IPTV, and it works totally fine with it.
