The one-line summary: a VPN is good at getting you back to your own subscriptions while you're away from home, and unreliable at unlocking other countries' catalogs. Anyone promising you the second thing is selling you something.
Why streaming services care where you are
Streaming platforms don't license a show globally. They license it territory by territory, and the contract obliges them to make it available in the countries they paid for and to make a reasonable effort to keep it out of the ones they didn't. That is why the same subscription shows a different catalog in Toronto than in Cleveland.
So when a service blocks VPN traffic, it isn't being spiteful. It is meeting a contractual obligation to the studio that sold it the rights. Understanding that explains everything else on this page — including why the blocking never stops.
How they detect a VPN
Mostly, by address. VPN providers own or lease blocks of IP addresses, and when several thousand accounts stream from one address in a day, that address is obviously a data centre and not a living room. Services buy or build lists of those ranges and refuse them.
There are secondary signals — a mismatch between your account region and your address, DNS resolving somewhere your address isn't, the timing patterns of a shared server — but the address list does most of the work. It also explains the flakiness: a server that works today can be added to a blocklist tomorrow, and a VPN provider's response is to rotate addresses, which works until it doesn't.
What reliably works
- ✓Getting your home library back while travelling. Connecting to a server in your own country so your paid subscription behaves the way it does at home is the single most reliable use, and the least contentious — you're a paying subscriber asking for the service you pay for.
- ✓Hotel and airport Wi-Fi that throttles or blocks video. Plenty of guest networks deliberately squeeze streaming traffic. Once it's inside an encrypted tunnel, the network can't single it out by type.
- ✓Free, ad-supported and news services. The less territorially licensed the content, the less anyone is checking.
What doesn't
- ✕Treating a foreign catalog as something you can count on. Some servers work with some services some of the time. Buying a VPN because a review said a particular pairing worked in March is a bad plan; that specific address may have been blocked in April.
- ✕Live sports blackouts. These are the most aggressively enforced rights in the business, often with additional location checks beyond your address. Expect this to fail.
- ✕Devices that can't run a VPN app. Roku, most smart TVs and game consoles have no VPN client. You can put the VPN on your router instead, which covers them — but then every device is on it, and any streaming service that objects will object to all of them at once.
- ✕Getting around paying. A VPN changes the apparent location of a subscriber. It does not create a subscription.

Is it legal, or just against the rules?
These are different questions and they get mashed together constantly. Using a VPN is legal in the US and most countries. Using one to present yourself as being somewhere you aren't generally violates the streaming service's terms of use — a contract between you and them, not a law.
In practice the enforcement people actually encounter is a proxy-detected error message. But "it's in their terms" is the honest framing, and a site that tells you otherwise is one you should trust less on everything else too.
Speed, and why 4K is the test case
Streaming is one of the few everyday things demanding enough to expose a VPN's overhead. Standard-definition and 1080p have enormous headroom on a modern connection — you will not notice. 4K is where a distant, busy server starts producing the spinning circle and the automatic drop to a lower quality.
The fix is almost always geographic: pick the closest server that satisfies whatever you needed the VPN for. A server in your own city costs you very little. One on another continent costs you a lot, every frame of the way.
If a service blocks you, try this in order
- Switch to a different server in the same country — the block is on the address, not the country.
- Clear the app or browser's cookies and site data for that service, then sign in again.
- In a browser, turn off location permissions for the site; the browser's own location can contradict your address.
- Use the VPN's own streaming-oriented server list if it has one — those addresses are rotated more often.
- Ask their 24/7 support which server is currently working for that service. This is unglamorous and it is usually the fastest path.
Where a big server network earns its keep
7,400+ servers in 118+ countries means there's usually another address to try when one gets blocked, and a nearby one when you need the bandwidth. NordVPN also has real Android TV and Apple TV apps, so the television doesn't have to go through the router.

The verdict
Don't buy a VPN only for streaming. The value is real but conditional, and no provider controls the other side of that fight. Buy one for the things it does deterministically — encrypting your connection on networks you don't own, keeping your browsing off your provider's ledger — and treat "my own subscriptions work while I'm abroad" as a solid bonus and anything beyond that as a coin flip.
