Hello Silvia,
In the description, my version of the firmware is shown.
I have two issues:
Issue 1:
I’m wondering if the card supports eSIM because the AT+QESIM command only enables eSIM, but any further command results in an error.
Issue 2:
My SIM card is not connecting to 5G. I tried the commands:
AT+QNWPREFCFG="mode_pref",NR5G
AT+QNWCFG="dis_4mimo_enable",0-1
I’m currently waiting for the ordered antennas, as I suspect the signal might be too weak.
Will the R12 firmware resolve the issue with eSIM commands?

R05 is an early version, I suggest you upgrade directly to the version I sent you and use the tools I sent you,and I hope you can click the for me,thx
Dear @aleksandar_kosak
I am not sure if you had download profile successfully, it need tool. Due to some limitation, I can’t share to you, you can contact with your provider to get.
You can use AT+QESIM=? to confirm which AT commands support.
For R12, I didn’t see it on my side, sorry about this.

Hello Silvia, please send me the original firmware for RM502QGLAA-M20-CASA, as my modem is stuck in EDL mode, and unfortunately, the existing firmwares I have are giving me errors during flashing. I have tried to contact the supplier, but unfortunately, I have not received any response yet.
By the way, I haven’t received any email from herbert.pan-Q yet.
Hello Silvia, please check and send me the original firmware. IMEI: 355878110055191
Dear @aleksandar_kosak
The original firmware is too old, it is not recommended to upgrade the latest firmware.
I will sent the original firmware to your email.
