Hello,

I would like to use the dual SIM functionality in Linux on EM7565. Currently, I am using it with NetworkManager/ModemManager but I can’t issue AT commands through it if it’s not in debug mode.

What would be a proper/easy way to use the DualSIM functionality in Linux? Are other DualSIM modems supported better?

Hi @bogdan,

You can use Linux QMI SDK APIs to manage active SIM slot DualSIM functionality in Linux on EM7565.

Check slot status:

Switch slot:  
SLQSUIMSwitchSlot  
Monitor slot changes:  
SetUimSlotStatusChangeCallback
