If someone made a screenless powerbank-shaped Android device, I might be interested. The device would double as a 5g wifi modem, and to access the UI you'd remote in over VNC from a laptop, or unrestricted mobile device like a PinePhone.
I'm using a tp-link M7000 with 4G, for SMS and wifi modem. A simple http page for send and receive SMS. I use the API to have my ZigBee gear SMS me.
I showed my dumb-phone to my bank and asked if I needed to close my account, suddenly card reader was still available as an option. If it becomes mandatory, they can buy me a phone.
It should not become the rule that we need a spy-phone, or any other BigTech services to take part in society. So I make my life hard work to defend that principle.
Hence I am hacking away with Zig on the PinePhone, since it has some nice hardware switches for switching off modem/GPS mic etc. But the modem itself is still a blackbox, so there will always be trust issues there.
