Hi peoplez. In my own design based on Q2686 i connect 2 simcard to the 1 module and switch between them using the GPIO pin. It works fine, but I need some more information how can I do this correctly, whith no possible collisions with Q2686 operating system and SIM physical data exchange. Does anybody help me? Thankz.
