Dual Sim Card
Hi,
I need to interface a second Sim Card to a mobile module (Motorola G20 or Siemens MC35, etc).
These modules only have bus for one sim. I was thinking of having some mux or switch i can control with my uC and connect one or another to the GSM module.
Any idea of device or approach for this?
Thanks,
Ric
