Please describe your issue below:

I have connected the RM500Q-GL, but when I run quectel-CM (as per VIM4 RM500Q 5G NR Module [Khadas Docs]) it says the SIM card cannot be detected (but it is definitely inserted).

Post a console log of your issue below:

What am I missing?

Is the green LED on the module bright?

It was, but the issue is now resolved. I don’t recall exactly what the issue was, but something in QSIMDET (or related functions) was configured wrong on delivery.
