No, it never worked with earlier NetworkManager versions either. As far
as I remember it was the same issue (nm kept polling for AT+CREG?). But
I never investigated further.

This is the most current Dell-branded firmware available, I apparently
cannot flash vanilla Novatel firmwares into the module.

Essentially your second patch with CREG=1 instead of CREG=0? Will do ASAP
