Personally, I'd advise against using VPN - especially if the VPN happens to be a free VPN. If you're getting connectivity issues with any of the websites you visit let alone frequent on the first port of call should always be whoever is giving you internet access and in which most cases it would be known as Internet Service Provider (ISP) for short. (Free) VPN at best only provides a temporary relief or workaround to your scenario unless you happen to live in a censored country like China but it is otherwise as secure as using any public WiFi your town/city/country/etc may provide.

You know otherwise there is almost always a scare story about using public WiFi - things like you should never do internet banking with it for instance. The same scenario applies with public VPN.
