Setting up Quectel 502Q - suggestions?

So I have SIMs for both Mobile Citizen and AT&T Postpaid tablet.

I keep both because the MC tower seems to have issues from time to time, but I know these Quec modems need ... identity support, to avoid problems. Is there a way to set up multiple profiles or would I be better off just buying a USB enclosure and plug it into my 1608 that houses my em7565 currently... then just use the 7565 for MC and 502 for ATT?

Any suggestions welcome!

You can setup connection profiles under the modem menu to recognize each SIM by ICCID or other methods.

Sorry for the late response.

My current plans have all SIM's registered to the various service providers for the same device, so I don't need to change 'identity' when swapping SIMS.

As for constantly re-writing NVRAM to change the IMEI, not sure the storage is designed for more than a few re-writes now & then. Maybe it's fine, but it also might shorten the life of the modem...

As an aside, here's a dumb question re: RM502q (and their ilk): The MHF4 connectors are for 4g & sub-6ghz (C-band) 5G antennas. If the modem supports mmWave 5G using those other rectangular-ish connectors, what sort of pigtail/connector is used for said mmwave antennas? Or perhaps those little rectangular doo-hikeys ARE the antennas (no pigtail or external antennas required?)...
