AirVPN and Mullvad share a very close number of servers, which are more than double the amount FrootVPN offer. Whilst each covers the basic necessities of a VPN, focusing heavily on privacy and personal security, AirVPN and Mullvad are the only two providers of the three which accept Bitcoin as a form of payment. Unfortunately, Mullvad do not currently have a mobile app in place and therefore it’s worth avoiding if you’re likely to use your phone as your main access device. FrootVPN boast about an impressive number of users globally (300,000), mainly due to their highly competitive rates, which are cheaper than both other options in this comparison. Mullvad only offer a monthly pricing plan, which means that longer term subscribers will not benefit from any discounts – something that customers can expect from AirVPN and FrootVPN.
