So I need a VPN that can let me use everything that is blocked as if I was back in the UK, like netflix, instagram, gaming, without any lagging at all, could someone recommend please?
Best option is your own instance of outline vpn set on your own rented vps.
Other than that I’ve heard red shield vpn works ok.
The best VPN is the one you make for yourself. Rent a virtual machine and deploy a VPN server based on some unsupported protocol. For example, shadovsock (ss) or Outline
I’ve changed 3 VPN providers last year, and was going to suggest exactly this. Works for now, and should be working for a long time.
