Some of the names on this list provide free VPN services or a free account option. This is normally a very limited version of the main product. However, VPNs that offer free trials will give you complete access to all features for a duration of time. This is the best way to decide whether or not a product is for you and can quickly be upgraded to the full thing at the end of a trial period. A free trial is usually a much better experience than committing to a completely free VPN.
