Private Tunnel VPN is an app that lets you access the Internet safely and anonymously. That said, to use Private Tunnel VPN, first, you have to take a few seconds to register with their service.
With the registration, you receive 500 MB of free anonymous browsing. If you want to continue after that, however, you have to buy credit. You can buy packs of 50 GB, 100 GB, and even 500 GB, depending on how much you need.
Like other VPN services, with Private Tunnel VPN, you can choose the country you want to connect to the Internet from. You can make it look like you're browsing from the United States, Spain, Mexico, and so on; all you have to do is change the country in the settings.
Private Tunnel VPN is a good VPN app. The only drawback is that you have to register to use it. But once you do, you get 500 MB of browsing data for free.
