I am looking to building my own phone from a SBC running a linux distro with plasma mobile and that can make calls. and I have some questions:
Where can I start?
Which SBC to choose?
How would I achieve the call functionality?

If you’re really against Pis, you could get one of the USB-controlled modules and try hooking it up to something like a LattePanda, but that’s going to be more expensive.
You could also theoretically get a cell modem chip from a company like Quectel and design the supporting add-on board yourself for any SBC of your choice, but I suspect that’s further down the rabbit hole than you want to go.
So, yeah, the Pi is probably the smartest choice if you really want to do your own hardware build instead of just buying a PinePhone.
