Hi, I installed a rm520n-gl on my R3 mini. It is detected but in quectel cm I always get SIM_ASBENT as status. Is there something I need to do to activate the sim card?

Thanks,

You can check the hardware first: after inserting the RM520N-GL module and SIM card, check whether the c9 pin has voltage.
