Mi Box 3 is slick. I'm using a paid vpn. sometimes free ones work too but they offer no encryption. the good thing about freebies is that if one doesn't work, you can always google another. opera, hma and hss are some of the free options though there are others, not to mention there are occasions when some might work and some might not. in case of paid options, ivacy, pure and express are some options. ivacy seems to be a decent option for now because of some summer sale it's hosting. 1 year plus another year under 50.

The other thing is, most of the freebies are proxies regardless of what they say. The reason is same, encryption but you can't really complain when they're free.
