Has anyone gotten a 4G modem to work on-board the NanoPC-T4?

This https://amzn.to/2Ue3BOC must work on Armbian OOB.

armbian-config -> network -> enable 4G connection
Which OS. I have the SIMCOM SIM7600E-PCIE module working with the T4 under Android.
Android is the target OS. Which Carrier?
I think the Quectel modem is supported out of the box with the T4 and Android 8. If you want to support another modem via USB, you need to build the OS to include the RIL for that modem. There is a generic RIL but I've never gotten it to work. Android doesn't support any modem out of the box and you will have to build your own custom OS for whatever you choose.

SIMCOM provide the RIL and all files needed to build support for their modems. If you use the SIM7600E-PCIE module and a USB to PCIE adapter, you can test it on the T4.

The RK3399 dev board has a PCI slot that takes a PCI Express modem. The SIMCOM7600E works in that for me but as I said, this is a custom build of Android 8.0 so support that modem.
