if you just need something free and quick then "hide my ass" has a free proxy surfer or if you need something to use for all your surfing needs like desktop and smartphone then you can get the paid version. which is really nice you can choose which country or even city you want to surf from.
I just signed up for Private Internet Access VPN; 1 yr, $40. I looked at several VPN reviews and settled on this one. I plan to use it while on vacation more for security reasons than privacy/location reasons. PIA does not have a separate iOS app at this time although I believe it is working on one. The service allows for 5 concurrent users which was a plus for my usage.
