"Free VPN services without software installation needed"
These services Works well in Windows and Mac, good for desktop sharing.
Don't support or don't fully support iPhone 4S, New iPad, Samsung Galaxy S III, Google Nexus 7 tablet, XBOX 360/PS3 game console, network players and home routers etc. And they are not pure VPN service actually.
First, I really like Teamviewer! But all of these software are actually desktop sharing applications, not the pure free VPN service.
I mean if you check several PURE Free VPN connections by search google, you will know what you can get from those true Free VPN connections, mostly they are using PPTP VPN protocol, works in all computers and smartphones, no client software download needed! green and organic! some of these services I found online are:
http://www.justfreevpn.com - Free VPN password online for USA, UK and Canada ( my favorite pick )
http://us.newfreevpn.com - USA Free PPTP VPN
http://www.getukvpn.com - UK Free PPTP VPN
Hope it helps for people who are looking for real free VPN connections! Anyway thanks for the nice article.
