> How is the Dual Sim feature is used in EM919X? is there a reference schematic that shows the pinout and the selection between two different sim cards while using the M.2 Interface? I’m also interested in EM7455, I saw that it’s pinout supports additional SIM, but I didn’t see that in EM919X, what is the reason?
