Can not detect external SIM on mangOH Red board

mangOH Red
1

Hi,

I am using external physical SIM(UIMS=0) on manOH Red board with Sierra RC7611, but for some reason RC7611 is not detecting external SIM. However I am able to see embedded SIM(UIMS=1) on RC7611. Also we tried with different physical SIMs, none of them worked in the slot.

See AT command response below:

Manufacturer: Sierra Wireless, Incorporated

FSN: 6M008285XXXXXX

OK

+CME ERROR: SIM not inserted

Does anyone know what could be issue? Hardware? or Sierra Module?

Thanks,
