I would like to find documenation related to the usage of ESIM for EM91.

I have a look on the ressources and i don’t find any revelant document to help me.

See if this helps

This integration is for windows, we aim to do that for an embedded products in linux, so it does not help.

you can verify if it works in windows first

BTW, have you checked “AT!UIMS=1” and “UIM2ENABLE” in AT!CUSTOM?

Hi On my em9191, I get

AT!ENTERCND=“A710”
OK
at!custom=“UIM2ENABLE”,2
OK
at!custom?
!CUSTOM:
GPSENABLE 0x01
UIM2ENABLE 0x02
IPV6ENABLE 0x01
SIMLPM 0x01
IMCONFIG 0x02
ICMPINTSRVDIS 0x01
OK

at!uims=1
ERROR
at!uims?
!UIMS: 0

Do you have any idea why i cannot set at!uims=1 ? Is my em9191 not support eSIM? I have two kind of em9191 with SKU 1104903 and SKU 1104629. Neither works.

Any hints?

Thanks

Hi,

THanks for you reply. I have tried set it to 0x01 but it is still the same error.

Alos, after connecting em9191 to Windows 11, I can see the UI to select SIM1 and SIM2 (esim). So, I have two more questions:

  1. Do you have other suggestions to use eSim on Linux?

  2. How can I customize or setup my eSIM profile?

Thanks

Have you tried in windows for the profile?

Yes, there are steps i can follow to add eSim profile in Windows. Do you mean I may be able to use eSim after adding profile in Windows?

You can give a try and see if it works
