To understand how a VPN protects your data, you need to look at the essence of a virtual network. So, when you install a VPN on your PC or smartphone and after going online, a so-called tunnel is created. On it, data from your computer is transferred to the VPN server where it is encrypted and only after that it is sent to the resource that you requested. Thus, no one will be able to find out what resource you visited, how long the session lasted, and what your IP address is, since the VPN automatically changes it depending on which server you are connected to. Surely more than once when trying to watch a video or listen to some music you came across a message that the content is not available in your country. Possible reasons: consequences of sanctions prohibition or denial of access by copyright holders. In any case, the solution to this problem can only be a change of IP address, which is what 适用于中国的最佳VPN2020 does. Not all providers offer bypass locks. Therefore, if you want to have access to all content on the Internet, pay attention to this function.
