Missing operator name

This was reported in email (https://lists.freedesktop.org/archives/modemmanager-devel/2022-December/009547.html) but I've seen the same issue and got a log. I'm using a Sierra RC7611 but the email mentions a SIMCOM_SIM7600G-H. mm.20221217.log

Operator ID = 310260: MCC = 310 MCN = 260 According to https://mcc-mnc-list.com/list this is "T-Mobile USA". However, there is a Verizon SIM inserted and if I do:

# mmcli -i 0
  -------------------------------
  General    |              path: /org/freedesktop/ModemManager1/SIM/0
  -------------------------------
  Properties |            active: yes

             |       operator id: 311480
             |     operator name: Verizon
             | emergency numbers: 911, 931313

So why is the SIM reporting a different operator to the modem?
