an ionos vps is £1.20 a month, no bandwidth limit, roughly 400 down and up speed, gives a single static uk ip address, and you can openvpn or wireguard to it from your mobile broadband router.
Dont know how you found them.
Both my VPS's one in USA and one in the UK I am planning to cancel as having recently gone through my monthly finances I noticed they have been upping the prices a lot and am paying just over £20 a month combined for 2 VPS's I dont use anymore.
The UK VPS was originally so I could run my own remote DNS server in the UK, and also to provide a proxy for a friend to watch UK content.
The USA VPS was originally for me to view USA netflix content.
In both cases they now blocked by streaming services, even just using the DNS server will get me blocked on prime video (whilst still using my home IP to connect), I assume there has been a blanket ban of datacentre IP's as they have no business in accessing streaming services legitimately.
But then I see Alex's comment above where this apparently works with ionos. O_o
I also dont need the private DNS anymore, as I used to DNSCrypt into it, but now I have DoH on cloudflare is no need.
