Hi
I have an EM7565 with 2 SIM cards connected tot he modem.
In the initial configuration of the modem with the firmware ‘01.00.02.00_GENERIC’ as it was delivered by Sierra, I was able to see the 2 SIM cards with :
qmicli -d /dev/cdc-wdm0 --uim-get-card-status
qmicli -d /dev/cdc-wdm0 --uim-get-card-status
[/dev/cdc-wdm0] Successfully got card status

But I was only able to connect with SIM card 1 that was configured as primary SIM.
So I searched for a way to swithc primary SIM.
I did it by using AT command AT!UIMS=0 or 1 (to select SIM1 or SIM2 as primary SIM).
But after that I have only one SIM card reported present by the command :
qmicli -d /dev/cdc-wdm0 --uim-get-card-status
It is only primary SIM taht is reported present (wether it is SIM 1 or SIM 2). I can still switch correctly from one to the other. I can connect with one or the other. But I can’t anymore have information on the secondary SIM.
I thought it could be a problem with the firmaware version and updated to V.01.05.01.00
But I have the same behaviour.
The qmicli -d /dev/cdc-wdm0 --uim-get-card-status reprots the SIM card as follow when 2 SIM cards are present in slots :
qmicli -d /dev/cdc-wdm0 --uim-get-card-status

I thought the problem could be that SIM2 is powered OFF but if you look at the reported status, it is “absent” status while the card is really present. It would be “powered-off” status if it was really powered OFF.
So my question : I know that we can only connect one SIM card at a time so it is not really a problem to see only the primary SIM that is the one we will connect. But is it correct to report secondary SIM absent while it is plugged ? I am not sure.
Morevover, this was working correctly (2 SIM s reported) before I used the AT!UIMS=0 or 1 command to select primary SIM. So the use of this command possibly chnaged some configuration in the modem itself resulting in only 1 SIM being showed by the --uim-get-card-status command. So is AT!UIMS=0 or 1 the correct way to switch primary SIM ? Is there another way that would keep both SIM reported present ?
Is it that I do things the wrong way or a problem in the firmware ?
Or is it on purpose that only one SIM is reported present ? In thta case, why are 2 SIM cards reported present while we do not use AT!UIMS=0 or 1 command ?
Thanks in advance.
