As a blogger recently I have published an article about the best IPTV service provider 2020 on a technology blog. For that article, I did a lot of research and tests to figure out some best IPTV service providers. Currently, there are 4–5 reliable and quality IPTV service providers on the market. I'll mention the top 3 of them in this answer.
Mainly, I select them for streaming quality, bufferless streaming, antifreeze technology, number of channels, number of video-on-demand contents, affordable price, device compatibility, refund policy, easy payment, and some others facilities.
IPTVtune: Overall & best value IPTV service provider in my eyes, offering 10K worldwide TV channels including two hundreds of premium sports and movie channels. I never face any buffering and problems during their trial period, VOD contents are almost up to date.
IPTVGEO: Another great budget-friendly IPTV service provider on the planet, but they have some lacking comparing IPTVtune. They have 9K TV channels. On the other hand, IPTVtune has 10K (not a big deal I think). 30K video-on-demand contents almost update to date too.
IPTVspring: Do you have kids in your home? they are accessing your Smart TV, devices a lot? Then you have to go with IPTVspring. They mentioned at their website that they’re a family and kids friendly IPTV service provider. They don’t provide any adult contents. But they have a great collection of movies, sports, and cartoons channels.
All of the above IPTV service providers I have tried during my research for a blog post. But after that currently, I’m using IPTVtune personally it seems too good to me.
If you want to tell me to suggest one of them, I’ll tell you to choose one of them according to your requirements
The recommendation is mine, but the decision is yours!
