How to Setup PVR IPTV Simple Client Kodi
Select TV (or Live TV if you are on a version lower than 15.2 and if you are then consider updating)
You will now see a pop-up saying that you have no PVR Client enabled. Select OK
Scroll down and select PVR IPTV Simple Client
In General select M3U Play List URL
Copy URL address of your M3U Playlist with options - HLS and paste it into the address section highlighted in the image below and select OK (the channels in this link probably won't work now. This is just an example to show you how it is done. You should use pastebin to find other links so you can create your own m3u.)
On your Home Screen you should now see TV (or Live TV if on an older version of Kodi). Open that to see the live channel list
The list should look like this. Select a channel for it to load, press play and Enjoy.
