I've been fooling around with Android boxes for several years now and tried about 6 different IPTV providers - can't remember all their names except IPTVtune, Broadband Services, HDPrime, OTT TV etc etc.
The best so far has been a likely lad in Morocco - IPTV Service . Thousands of channels from all over the world but I am mainly interested in sport and get coverage from the UK, Australia, New Zealand, USA and South Africa channels. They also have an extensive library of movies and TV series. Cost is 1,900 baht per year paid by PayPal or Western Union transfer.
At present I am also using a similar, but not as reliable, service from Reliable Iptv Provider. Premium Channels and VOD| Broadband Services as a backup. It's a bit more expensive, I think 2,900 baht/year, and also has a good VOD library.
Most of them have trial options. They are all in the dodgy zone legally and one must accept that they could disappear at any time. Communication is usually on the Telegram app.
