Hi all,

I feel like I may be missing something about how SIM cards work here, but I’m unable to figure out how to load the ISIM application on my SysmoISIM-SJA2s, so I’m reaching out here for some help. 

I started with pySim-shell and listed the directories under the MF directory and it shows only ADF.USIM, so I decided to use shadysim_isim.py to list out the applications on the card and was shown this:

The SysmoUSIM/ISIM manual pointed me to Annex E of 3GPP 101.220 which says the prefix of the ISIM application is A00..00871004.

So my questions are:

Am I missing something and the app is installed?
If not, is there a way to load and install the ISIM application?

Thanks in advance everyone.
