I purchased the LTE modem and trying to use it with VIM3 and m2x extension board (with ethernet). However, while I believe the modem is being found by Ubuntu V20191231 eMMC. Anyone have a guide on how to get the LTE modem and Linux configured to access the internet via LTE?

Yes the modem is detected and assigned ttyUSB for access.
To configure it you will have to follow AT commands from the modem manufacturers guide.
For that you will need atinout package.
If you want to use a gui then you can download modemmanager and use it instead of cli.
I cannot confirm if these packages will be present in ubuntu distro, if it’s not present then you might have to compile it yourself.
Shutdown, removed power, waited 5 minutes. plugged back in. still nothing same error. I can run mmcli and see that with both carriers the device is registered and it picks up the right number and signal status.
root@Khadas:~# sudo mmcli -m 0
