Using grapheneOS WiFi only and somehow disable the radio modem would be best.

I really only need to use my phone as a "computer" at home over VPN and tor for amethyst and Bitcoin Lightning.

Hate the experience on desktop for both due to various reasons.

Pixel 8 pro has an amazing camera for sunsets, landscapes, and nature etc.   Don't need any connection for that photography either till ireturn home.

I am very happy with my pixel and graphene
Thanks for the advice and for everything you do for the world.
