IMSI not supported on EM7511


I’m running EM7511 in conjunction with a OpenWRT running on a Pi and I’m trying to find out what the IMSI of the SIM is. Unfortunately it says “Not Supported” when I pass the command below using uqmi.

 root@OpenWrt:~# uqmi -d /dev/cdc-wdm0 --get-imsi
"Not supported"

Anyone knows how I can get this to work?

Thanks in advance.
