Even if you have a Netflix in USA account, you won't be able to start streaming or watch TV shows on Netflix if you're out of the country. The same is true for other streaming services like Apple TV and Hulu. This is why you need to use a VPN to access Netflix while you're travelling. The best VPN to do this is NordVPN. It has a 30-day money-back guarantee and all the other features you need to watch TV shows or start streaming from Netflix.
Other benefits of using a VPN include unblocking other content streaming sites, protecting your data and making it appear as though your location is different from your physical location. You should use your VPN all the time, but especially if you're using public WiFi or if you're trying to unblock restricted content. Public WiFI hotspots are notorious for not being secure and letting hackers in. This leaves your personal information and your internet browsing data vulnerable and available for anyone who wants it.
