Is IPTV free or paid?

I’ve been hearing a lot about IPTV lately and I’m trying to figure out how it works in terms of cost. Some websites and forums mention “free IPTV” services, while others talk about paid subscriptions that promise more channels and better streaming quality. I’m confused about the difference between free and paid IPTV,are the free ones reliable, or do they come with risks like poor quality or legal issues? And for the paid services, is it usually a monthly fee, yearly, or one-time payment? I’d love to hear from people who use IPTV regularly about the pros and cons of free versus paid options.
