You'll need a VPN if in the USA – TennisTV – Live Streaming Tennis Review

I bought a one month subscription and was quite pleased with the first week. But in the second and third weeks, almost every tournament except WTA Moscow has been geoblocked. So, essentially, even though I paid for a subscription, I can't watch the matches because I'm in the US. So, just be aware of the fact that you'll have to also pay for a VPN to gain access to the matches. That's ridiculous, but probably not TennisTV's fault. Other than that, the live matches (that I'm not blocked from viewing) stream very well on my iphone. My other complaint is that there is no "on demand" function like there is on the computer.
