By using a VPN you have many advantages, which are weighted differently depending on your personal use case. When you use a VPN, you can always choose which server from which country you connect from. For example, if you are currently in China and you want to use Facebook, you can’t do so because China has blocked Facebook. But with a VPN you can connect to a different server world wide and like this you can connect to facebook and also surf anonymously.
If you want to use Booking.com in Turkey to book your accommodation, this is not possible because Turkey blocks Booking.com! If you use a VPN, however, this is possible. These are two examples where it makes sense to use a VPN to access websites that are blocked by the individual governments in the countries.
Furthermore, you can also access public television channels in other countries and thus watch sporting events or other movies live and free of charge. If you are outside of Germany or the EU, for example, you can connect to a German server via a VPN and still watch SKY, DAZN, ARD Mediathek or the ZDF Mediathek in live stream or via recordings. You have another advantage if you want to access more movies in streaming portals such as Netflix. By using a VPN, more movies and series are available to you.
