How or which vpn can one use also for netflix?

Otherwise there's always an error message with netflix at normal VPN apps I find in the store

Netflix is actively spamming VPN providers.
Background: Not all content is always licensed for all countries - therefore Netflix must ensure that only the countries / regions that are licensed are presented with the content.
Because this can be bypassed via VPN, Netflix actively spews out the IP ranges of VPN providers.

Can't you do anything or use something else?

You already understood what you want to tell you, right?

Nord Vpn is great but has its price

Yes

"NoRdVpN iS SuPeR hAt tHe SeInE PrEiS"

NordVPN is cheaper than cheap. With PP can probably bring here a price argument.

As @TheHeckler said, IP ranges are locked out.

So if really no VPN works. Simply rent a cheap VPS for 3 euro a month somewhere and gossip OpenVPN on it

Zack and ready
