If you want to watch Spanish Netflix, all you need to do is sign up for the service and go to their website.
However, you may find that your internet connection slows down significantly when you do that. This can happen if your internet service provider (ISP) decides to throttle (slow down) your connection. ISPs often put a cap on your bandwidth when they see you streaming or downloading files.
You can use a VPN to avoid being throttled when watching Netflix or downloading files. A VPN hides your internet traffic even from your ISP, so they don’t know what you’re doing. This way, you can stream without being throttled!
