Check out my thread on the topic:

[Clearfog Pro - MPCIE LTE Card (Quectel EC25) Not Detected](https://community.solid-run.com/t/clearfog-pro-mpcie-lte-card-quectel-ec25-not-detected/400/1)

The TLDR is:

1. The EC25 uses USB, and the mPCIE slot with sim (near SOC) is not connected to usb. The sim slot you are using applies ONLY to the mPCIE slot closest to the SOC.
2. The far mPCIE slot supports USB, but the SIM slot does not come soldered to the clearfog board. You need to solder a holder to the board or use a mPCIE sim adapter.

Details are in my thread.
