Free VPN services are required because sometimes your school/ office might have blocked certain websites like social networking sites or job search sites. Typically people use proxy sites to get around such problems. However proxy sites suffer from the problem of unreliability. It is really difficult which proxy sites are safe and which are not.

Certain websites are available only in a particular country. For example there are number of internet sites that allow only visitors from USA to watch entourage online. VPN services allow you to bypass these restriction as the VPN service can hide your real real IP thereby making the site to think that you are a US visitor.

There are a large number of good VPN services available for a nominal fee. However I am assuming that you are looking for a free VPN service and hence we will talk about some popular VPN services that are free.

Alonweb is one of the best free VPN provider. It works by hiding your real IP address and thus enabling you to visit some restricted websites. On the negative side AlonWeb injects advertisements to the page being viewed. Free users are allowed to transfer 1GB of traffic every month. That should be enough for most practical purposes.

UltraVPN is another free vpn service provider that enables you to access restricted websites. There is no limit on traffic and hence you can use it to watch cricket or movies online.

this is another VPN service that does not charge any fee. Let me know if I should have included some other free VPN service in this list. I will update the list accordingly.
