Disabling eSIM

Fri Oct 23 11:49:08 UTC 2020

Hi all,
I have a possible problem related to eSIM on a Qualcomm X16 modem.

ModemManager reports:

Oct 23 09:34:44 3a062c2 ModemManager[29935]: SIM is missing and SIM hot
swap is configured, but ports are not opened.

But I only got to this point after I modified the NTB buffer size as
reported here;
https://github.com/jakeday/linux-surface/issues/306#issuecomment-518898603

After doing that, I get the above problem. And another user there said in
https://github.com/jakeday/linux-surface/issues/306#issuecomment-580665664
that he needed to "unselect" the eSIM in Windows.
So my question is now, since I do not have Windows installed on that
machine, how can I disable the eSIM from linux?

Thanks in advance
