Quectel RM502q-AE not connecting to Verizon

I have a new Quectel RM502q-AE in a new router.

It appears that the modem is unable to “register” on the network, and it shows “No Service” in an area where service is known to be good. I have tried different SIM cards that are known to be good, this didn’t help. I suspect the firmware needs to be updated.

I installed the module in my laptop, but I don’t have the Windows driver so I can’t troubleshoot any further.

I’d like to get the Windows 10 driver and the most current firmware. I would very much appreciate any other suggestions you may have.

Thank you for your assistance
