PCIE mode in new 5G modems

[Bruno Antunes]

Hello,

Has anyone tried the PCIE mode on the newer 5G modems?
I have tested with both the Quectel RM500Q and the SIMCom 8202G with no success.
The Quectel model is detected by the modemmanager but can't establish
a connection:

The SIMCom modem also should support the PCIE mode  but the
modemmanager does not detect it.

Is something missing? Is anyone working with this?
Thanks.
