Not exactly what you’re after, but the Librem 5 (crowd-funded, at the head-scratching stage) aims to put the baseband processor in an optional M2 slot with killable power. On a device that runs Debian. From following progress on that project I’ve got the impression that everything to do with chips for mobile connectivity are so patent/IP-law encumbered that there’s little hope for Free Software replacements.

However, hacking on that handset is the best chance I’m aware of for you getting the device you want (perhaps with something else in the M2 slot).

- subway 8y agoI think only the prototypes are using M2. The production devices likely won't have a removable modem, but it will still be a separate chip with separately controllable power.
- jrcii 8y agoThe Neo900 has a completely sandboxed baseband, and you can kill the baseband with the Dragonbox Pyra. Both are on their way.
