PySim-shell: File not found errors

Hi all, I'm using pySim-Shell with a SysmoISIM-SJA2 as well as a SysmoUSIM-SJS1 and on both cards I get quite a few "File not found" errors trying to access different EFs. I'll use EF.NCP-IP as an example to illustrate the issue I'm having below. My initial steps when I plug in the card are as follows: 1) ./pySim-shell -p0 2) verify_adm <adm1 key> 3) select ADF.USIM Now when I run "dir" in ADF.USIM it lists a number of EFs I'm interested in, including EF.NCP-IP. Since this requires service number 80 to be available in EF.UST, I run "select EF.UST" followed by "ust_service_activate 80". This runs without issue. When I run select ADF.USIM now followed by select EF.NCP-IP, the card returns a "File not found" error. So my questions are: Is this file not supported on the SJA2 and SJS1? Is there a way for me to add those files to ADF.USIM? Is there a list of the known supported EFs of the SJA2 and SJS1? I looked and couldn't find anything. Thank you in advance!
