We have a machine with an on-board SIM slot.
We are running Ubuntu 22.04 LTS fully updated.
We are able to use this on-board slot with the EM06-A units that we have used previously. (works great, btw 
) The physical SIMs we installed are all recognized by it – both the North American and the Brazil SIM (we know the Brazil SIM won’t work properly with the EM06-A but the system still recognizes the SIM).
Neither of these SIMs are recognized with the EM060K-GL installed (we have tried 3 distinct units).
We even tried changing slot priority on the EM060K-GL (JIC) which had no effect.
The SIMs are from Hologram for IoT data upload.
Here is the equipment, status and slot reports from mmcli (equipment id redacted):

We have looked for firmware updates in case that was an issue but were unable to find any.
Any ideas or troubleshooting we should try?
TIA.
