Access to VPN Unlimited is not free; it is a subscription-only service. However, there are other virtual private networks (VPNs) that offer free service, with limitations, but can be used as another means of connecting to a secure network.
The infinity price of VPN Unlimited, which allows an indefinite amount of bandwidth to be used, is available for a one-time purchase price of $499.99 as of 2015. VPN Unlimited also offers lower-priced subscription services that start at $1.99, as of September 2015.
Free VPN services include CyberGhost, VPNbook and Hotspot Shield. Each service has its own limitations for its users, which either have advertisements or bandwidth limitations. The advertisements allow the services to remain free for its users, while the bandwidth limitations can cut off how much a user can use the service.
