Replaceable baseband modem: can it be swapped for a dual sim module?

Since the baseband modem of the Librem 5 will be replaceable, does this mean that we can swap it for another one that has dual sim support?

In theory, yes. But if such a device would exist, Purism would most likely make it available to us.
It is my understanding that those M.2 modules exist for things like IoT devices. They are not intended to be used in mobile phones. There is not really a market for such modules with two SIM slots.


The SIM card slot is not placed on the modem, it’s part of the phone mainboard. So it’s rather unlikely you’re going to be able to stuff another one in, without some serious hacking or emulation (if that’s even possible).
