Help on reading values of ISIM
by 程子帅 23 Jun '21

23 Jun '21

Dear Osmocom community, I am using pysim to read values of ISIM. However, it just returns "None, None". And the aids of my SIM card is ['a0000000871002ff86ffff89ffffffff']. It seems does not have ISIM application on my SIM card. How should I read values of ISIM? Best regards, Zishuai CHENG

PySim-shell: File not found errors
by bryan coxwell 07 Jun '21

07 Jun '21

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!

No ISIM application on SysmoISIM-SJA2?
by bryan coxwell 06 Jun '21

06 Jun '21

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: AID: a0000000620001, State: 01, Privs: 00 AID: 4a6176656c696e2e6a637265, State: 01, Privs: 00 AID: a0000000620101, State: 01, Privs: 00 AID: a0000000620102, State: 01, Privs: 00 AID: a0000000620201, State: 01, Privs: 00 AID: a000000062020801, State: 01, Privs: 00 AID: a00000006202080101, State: 01, Privs: 00 AID: a0000000620002, State: 01, Privs: 00 AID: a0000000620003, State: 01, Privs: 00 AID: a000000062010101, State: 01, Privs: 00 AID: a00000015100, State: 01, Privs: 00 AID: a0000000090005ffffffff8911000000, State: 01, Privs: 00 AID: a0000000090005ffffffff8912000000, State: 01, Privs: 00 AID: a0000000090005ffffffff8913000000, State: 01, Privs: 00 AID: a0000000090005ffffffff8911010000, State: 01, Privs: 00 AID: a0000000871005ffffffff8913100000, State: 01, Privs: 00 AID: a0000000871005ffffffff8913200000, State: 01, Privs: 00 AID: a0000000090003ffffffff8910710001, State: 01, Privs: 00 AID: a0000000090003ffffffff8910710002, State: 01, Privs: 00 AID: a0000000090005ffffffff8915000000, State: 01, Privs: 00 AID: a00000015141434c, State: 01, Privs: 00 Instance AID: a00000015141434c00 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.
