The following VPN services have a free mode, but remember that somebody has to pay for the bandwidth, hardware and maintenance.

One way or another they will get their money, mostly by trying to get you to upgrade limiting what you can do, for example, no video streaming or P2P. Other providers will show advertisements, and one or two could be a scam logging username and passwords. To ward off fraud it is best to stick with VPN companies that have been around for a long time, tell you who they are and how they make their money.

Free VPN for iOS and Android

Tenta browser: Currently only for Android (other platforms to follow). PIN protected privacy browser with a free unlimited built-in VPN, Incognito browsing and encrypted visited pages storage.

VPNhub: A VPN provider with multiple servers and unlimited bandwidth. There are only two catches, one is that the desktop version requires a paid subscription, and two is that the VPN is using advertising to finance the cost of providing the service. If this bothers you, buy the premium version.

Opera browser: Not really a full VPN, the Opera browser for Android and iPhone can hide your IP when browsing the Internet but it will not protect you for any other apps in your phone. Be aware that the logging policy is not clear and that a Chinese company owns Opera, not the best location for privacy.
