With Proton VPN, you can change your IP address to make it look as though you are accessing the internet from Spain by connecting to any of the 16 servers located there.
To select the fastest server in Spain for your location, open the Proton VPN app and double-tap the marker in Spain on the map in the VPN interface. If you prefer, you can also select a specific server to connect to from the list of servers in the sidebar.
