Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

If you want premium channels, you likely wont find that for free. You can get cheap iptv from online stores for a few bucks a month. I dont recommend the ones that have their own website, as they markup the price a lot for the same service that you can find on online storefronts like g2a or z2u. They are resellers, but its a good first step until you can find a private provider which will give higher quality streams and better epg. I also recommend dispatcharr like a lot of other comments was saying, that will allow you to easily connect it to jellyfin in a format it understands. Oh and if you go the z2u route, ask for a trial before you buy, all good resellers will give you a free trial that last from 8 hrs to 24hrs to see what channels they have and verify the stream quality. Lmk if you have any questions.
