If you want the operator name of your SIM card, you can use
--nas-get-home-network. If that reports that it's unprovisioned, you
can always try to parse the first 5-6 digits of the IMSI and match
them to the MCCMNC of your expected operators.

If you want the operator name of your network provider, you can use
--nas-get-operator-name, or otherwise use --nas-get-system-info to
retrieve the MCCMNC, and then use --nas-get-plmn-name=[mccmnc]
