Thanks.  I noticed a couple of possibly interesting things.

AT_OLCC apparently controls unsolicited call status, and is off by
default on my GTA04:

_OLCC: 0

I wonder if it's what's needed to avoid the call state polling that was
discussed here:

AT_OPATEMP reports the temperature near the power amplifiers, and its
documentation indicates that there is a 'safe' value.  I wonder if
exceeding that value might possibly cause a reset?

AT_OGPS controls whether the modem's GPS is on, which would obviously
use some unnecessary power - but I checked that on my GTA04 it's off:

_OGPS: 0

Just a few thoughts....
