Travelling stresses a VPN differently from home use. You connect from networks you do not control — hotel, airport and cafe Wi-Fi — on whatever device is in your pocket, often in a country you have never connected from before. So this ranking weighs the facts that decide that experience and can be verified on each provider's official site: how many countries and servers you can connect through, how many devices may connect at the same time, whether there is a usable free plan as a backup, and how long the money-back guarantee runs if it does not work out on your trip.
What this page deliberately does not do: promise that any provider opens any particular service from any particular country, or that it bypasses any network restriction. Providers rarely guarantee that themselves, and services and networks change their detection constantly. We also publish no speed-test numbers we have not measured ourselves.
