How can I bypass geoblocking for free?

Hi, I'm just out of Europe on vacation, and Netflix does not let me look a lot of stuff. There are many apps that can bypass the so-called geo-blocking, but they all cost money. Is there another method against it? Or do you know an app which is free / works?

With TunnelBear you have a few MB free, then you have to pay. Of course, money, service, support and servers cost money.
