I think I am finally understanding these used modules I have gotten.
These have prior settings in the module that needs to be erased.
This command showed a lot of the prior owners stuff.
qmicli -d /dev/cdc-wdm0 -p --wds-get-profile-list=3gpp
I think the fix is from here https://wirelessjoint.com/viewtopic.php?t=1269
In my case I stopped ModemManager
systemctl stop ModemManager
Then launched minicom
minicom -D /dev/ttyUSB2
Then I ran the following
AT!ENTERCND="A710"
AT!RMARESET=1
I waited then actually rebooted the whole machine, I think all I needed to do was reset the module.
When it came back up I went back in to minicom and ran
AT!ENTERCND="A710"
AT!SELRAT=06
AT!BAND=00
AT!RESET
All those profiles were gone
Also checked
AT!GSTATUS?
And low and behold it was registered.
Started up ModemManager and I was golden
