How to test a site "from" another country?

There is a service called Tunnel Bear , they allow you to install small application on computer, choose country where you want to "visit from" and then look at web sites as user from that country.

Also, there are lots of premium VPN solutions (i.e. ExpressVPN) which can be used to simulate this. It's pretty intuitive and easy to use. I think they have free account with some limited bandwith. @Carl_Whalley, if you want give it a shoot, hope it helps.

Finally, you can use Hoxx VPN proxy (installed as an free add-on for Mozilla) where you can choose multiple locations and change your IP.

Best and simple solution, works perfectly to me. http://www.locabrowser.com/
