Without any second choice, you should got with paid VPN service providers because free VPN come with very limited features where there are thousands of people are using the same server which makes your internet connection extremely slow. Other than slow speed, free VPN also places adverts on web pages to earn money, they offer your very limited internet speed and very few features.

Free VPN service providers also provides you the list of very limited countries and it is not necessary that they offer you the country you are willing to connect with.

On other hand, paid VPN service providers offers you many features and option to surf internet without any restriction.

The less users use the server, the more internet speed  you will get. The main advantage of using paid VPN that they allow you to download, seed and upload torrent files.
