@herbert.pan-Q What is the latest firmware for RM500Q now? Can the firmware be downloaded on the web site?
And, do all RM500Q variants have full e-SIM support now, for downloading e-SIM profile into eSIM like described here Use an eSIM to get a cellular data connection on your Windows PC - Microsoft Support and using eSIM?
Any followup on the Which Quectel modems have eSIM / eUICC functionality? Do Quectel models have different levels of e-SIM support? How use e-SIM? thread would be appreciated.
