I am trying to get a Quectel EP06-A working on a 922UAGS-5HPacT (NetMetal 5 triple) without success. I installed the modem but it is nowhere to be see (no lte interface, nothing on /ports/print, etc. ). I also upgraded to 7.1beta5 but the same.
Check first System > Resources > USB - do you see detected a mPCIe card ?
Check next the Interface > LTE > Mode is auto or serial ? (auto is best)
Do you see the System > Ports > usb interfaces or Interface > LTE > lte interface ?
Those are proper stuff for first diagnostic.
You can add logging by: /system logging add topics=lte
And check after reboot if any LTE logs exist.
This means your RB not detect that device at all.
You should try use USB-mPCIe adapter and check if that lte module works with Windows. You can contact to seller of module about latest firmware and Drivers for see proper COM devices.
At some RB like LHGGR people sometimes not see a lte module by that thermal pad - that’s why good way is first check lte module in usb adapter.
