The NITZ notification does indeed arrive unsolicited.  However, no AT
modem that I know of reports the received NITZ name.  This is only
reported via COPS.  The best you can do is call COPS again after the
driver reports ofono_netreg_time_notify.

Hence the reason for my pointed questions.  I'm a big proponent of
moving the PLMN database to the core, however this needs to work for
both ISI and AT modems.
