That only means you can't do it without some modification of the
motherboard and module.
I was planning on building my own linux based phone from components
before I found this project. Assembled from modules, it would not be
hard, just the sofware side would take time... Right..? So I also
thought about this multi-sim thing and I concluded that the protocal for
talking to a sim is available.. Indeed, you can build something to copy
the sim to your laptop if you wanted... So I thought of making a virtual
sim software which would store and allow switching between multiple
copies of sims...
Then you wire the sim interface from the gsm module to gpio on the
processor and write the necessary driver to make it look like a sim.
The technical aspect isn't really that hard. Just time consuming.
