What carrier are you using?
Does carrier support your modem, imei?
Does carrier require provisioning before imei can be on network?
What drivers are used? # lsusb -t
Can you run get home network?
Paste results from --dms-list-stored-images
What is result from --dms-get-power-state
When manual, issue --wds-set-ip-family=,4
After manual run, issue cmd --wds-get-current-settings
Remember to run all with -v while troubleshoot.

I ran into similar issue, with internal error, it was carrier not liking my
modem.
