If you are not too worried about privacy and just want to appear in another country or get around your cafe's system blocking some pages, I use hotspotshield.com or occasionally hideme.com in their free forms. Hotspotshield is actually quite handy. I just had to use it to access https://www.privateinternetaccess.com/ as Pret a Manger had decided that deserve blocking for some reason. Hideme seems kinda unreliable but works sometimes.

I don't know if I get the whole privacy thing - if you're just browsing HN etc like me why bother and if you want to do criminal stuff I gather it's better to use a completely separate machine with no personal info on. Or someone said Tails OS.
