The PinePhone modem is from Quectel, the ARM processor in the modem is by default a proprietary Linux distro, but you can replace it with an open source Linux distro. Unfortunately the Hexagon DSP in the modem runs a proprietary OS.

- squarefoot 4y agoI'd not complain even about a 100% closed modem, if my data would be en/decrypted before entering and after exiting from it, so that all it sees is noise, and it has no way of interfering with the hosting main OS. If they document it enough to make it fully usable from a FOSS environment, that is, no traps like "...but it works better with our new shiny (and 100% closed) OS...", then I'd be ok with that.
- pabs3 4y agoUsually the modem is the thing that implements SMS and phone calls, so it probably wouldn't be possible to do that. You could of course start a VPN and do VoIP and messaging apps instead but then you'll still be getting SMS and phone calls.
