Update: I just enabled WiFi calling on Freedom using my Pixel 9. If you're using this carrier the issue is with your phone. Evan Leibovitch, Toronto Canada @evanleibovitch / @el56 On Wed, Dec 10, 2025, 02:15 Ron via Talk <talk@lists.gtalug.org> wrote:

That's not the case with most ARM platforms, especially in phones. The on-device firmware is extremely minimal, and the OS itself is expected to know the inner workings and intricate details of the hardware.
I think kinda disagree here.
My understanding is that the modem firmware - and everything controlling the SoC - are essential to the device.
Also quite difficult to replace because they're unreachable at layers below Android, and also because they're quite complex.
Perhaps my understanding is incorrect?
