Airalo esim does not work even after showing as activated.

So I bought their UK esim (2GB option with some voice and smses as well). Activated it, shows all is fine and active but 0 signal/use. Have restarted phone, done everything on their help pages. I'm not the first to experience this with them. Won't buy from Airalo ever again, that's $8.5 USD down the drain.
