EG915U second sim usage

Hi everyone
I’m trying to use second sim of EG915U, but can not find any at command to switch between sim cards in EC200&EG915U AT command manual.
I tried AT+QDSIM=1, but module return “invalid command line” in response.
Firmware version of my module is “EG915UEUABR02A04M08”.
Do you know how to switch between sim cards?
Thanks in regard

I will email you the latest firmware, you can try it, thanks.
