sysmoISIM-SJA2 applet install
by mail＠micahflack.com 06 Apr '26

06 Apr '26

Hello! I tried searching the mailing list to see if anyone else has had this issue, but I didn't find anything relevant. Explanation: I am trying to install my java applets to an older sysmoISIM-SJA2 card with the "SELECTABLE" and "DEFAULT" privilges/flags. The reason being that I need my applets to auto select itself rather than manual interaction through the SIM Toolkit menu. Currently, I am using the shadysim-isim tool to load my applets, however, there is no option to make applets defaultSelect. And, it doesn't look like pySim supports this currently either. GlobalProtectPro (gp.jar) does have support for these cmds, but it looks like they need addtional parameters specific to the SJA2 when installing. Does anyone know what the exact parameters needed are? Someone else noted this issue under the GlobalProtectPro repo - but I'm not really knowledgeable enough to understand what was said. Link to the issue: https://github.com/martinpaljak/GlobalPlatformPro/issues/293 Link to their solution: https://github.com/martinpaljak/GlobalPlatformPro/issues/293#issuecomment-1… Thanks!

Supported Phone Models Simtrace 2
by Nico Naudé 26 Feb '26

26 Feb '26

Good day, I have been trying to get Simtrace2 to connect to a 'newish' phone model, but to no avail. I can not get the SIM to be recognised in the tray (I confirmed that the ribbon flex cable's continuity is OK too). I saw a sysmocom thread <https://osmocom.org/issues/6181> where a Google Pixel 5 succeeded in tracing some TPDUs. Does anyone have some hints as to how to get this working on a non-M.2 form factor modem and ideally in a handled? I have tested with the following phone models, all with the same result of no SIM detection: Google Pixel 3A & 5, Samsung S21-S24, iPhone 13 & 14 and OnePlus 9 Kind regards, Nico

Der Harald Welte First of all thank you for your reply. I tried again today and now I have this problem. Early preparations: Create a linux (debian11) (this server server) Install the following dependencies osmocom-latest_1.0.0_amd64.deb libosmocore20_1.8.0_amd64.deb libosmocodec0_1.8.0_amd64.deb libosmoisdn0_1.8.0_amd64.deb libosmogsm18_1.8.0_amd64.deb libosmocoding0_1.8.0_amd64.deb libosmovty9_1.8.0_amd64.deb libosmogb14_1.8.0_amd64.deb libosmoctrl0_1.8.0_amd64.deb libosmosim2_1.8.0_amd64.deb libosmousb0_1.8.0_amd64.deb libosmocore_1.8.0_amd64.deb Then I cloned two linux (debian11) one for the card reader part (bank) and one for the client-st2+simtrace2 part. bankd install dependencies libosmoabis10_1.4.1_amd64.deb libosmo-rspro2_1.0.0_amd64.deb osmo-remsim-bankd_1.0.0_amd64.deb Installed pcscd, opened pcsc and set "1", "0", "HID Global OMNIKEY 6121 Smart Card Reader \[OMNIKEY 6121 Smart Card Reader\] 00 00" in the csv file I run the program and wait till this root@debian:/bin# sudo lsof -i :9999 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME osmo-rems 469 root 4u IPv4 12597 0t0 TCP *:9999 (LISTEN) root@debian:/bin# osmo-remsim-bankd -i 192.168.2.122 -I 192.168.2.105 -n 1 -b 1 2329 DMAIN INFO bankd_pcsc.c:105 PC/SC slot name: 1/0 -> regex 'HID Global OMNIKEY 6121 Smart Card Reader \[OMNIKEY 6121 Smart Card Reader\] 00 00' 2329 DRSPRO INFO ../rspro_client_fsm.c:307 RSPRO_CLIENT(server){REESTABLISH}: Creating TCP connection to server at 192.168.2.122:9998 2329 DLGLOBAL ERROR socket.c:933 unable to bind socket:192.168.2.105:9999: Address already in use 2329 DLGLOBAL ERROR socket.c:945 no suitable addr found for: 192.168.2.105:9999 root@debian:/bin# osmo-remsim-bankd -i 192.168.2.122 -I 192.168.2.105 -n 1 -b 1 -P 1314 2333 DMAIN INFO bankd_pcsc.c:105 PC/SC slot name: 1/0 -> regex 'HID Global OMNIKEY 6121 Smart Card Reader \[OMNIKEY 6121 Smart Card Reader\] 00 00' 2333 DRSPRO INFO ../rspro_client_fsm.c:307 RSPRO_CLIENT(server){REESTABLISH}: Creating TCP connection to server at 192.168.2.122:9998 2334 DBANKDW INFO bankd_main.c:442 [000 INIT] Changing state to INIT 2334 DBANKDW INFO bankd_main.c:442 [000 INIT] Changing state to ACCEPTING 2333 DLINP NOTICE input/ipa.c:141 192.168.2.122:9998 connection done 2333 DRSPRO NOTICE ../rspro_client_fsm.c:127 RSPRO_CLIENT(server){REESTABLISH}: RSPRO link to 192.168.2.122:9998 UP I first checked port 9999. This is the port on my bankd side, and it shows that it is being occupied by osmo-remsim. Because I read your reply that you need to bind the local port now, so I set -I, but when I set it like this, I enter the first command, it shows that my port is occupied, bankd can’t start, when I try it for the second time. The port -p 1314 is specified, and bankd is successfully started, which can also be seen in the banks of the server. But client-st2 reads port 9999, which is very contradictory.I think port 9999 of bankd is the same as port 9998 of server. It should not need to be set, but if it is not set, it will prompt an error! Why?

Hello I can access my ZTE Modem and read values from the SIM card like IMSI with AT commands. Welcome to minicom 2.8 OPTIONS: I18n Port /dev/ttyUSB2, 18:23:09 Press CTRL-A Z for help on special keys AT OK AT+CSIM=? OK ATI Manufacturer: ZTE INCORPORATED Model: MF626 Revision: BD_MOBINILP673M3V1.0.0B02 IMEI: 357034037160973 +GCAP: +CGSM,+FCLAS I would like to try pySIM-shell to access the same modem with SIM, but I am getting the error below: (venv) root@ubuntu-HP-Notebook:/home/ubuntu/pysim# python3 pySim-shell.py --modem-device /dev/ttyUSB2 DEBUG:root:Sending AT command: AT INFO:root:Command finished with timeout >= 0.2s DEBUG:root:Command took 0.201042s (89 cycles a 0.002000s) DEBUG:root:Got response from modem: [b''] Traceback (most recent call last): File "/home/ubuntu/pysim/pySim-shell.py", line 1117, in <module> sl = init_reader(opts, proactive_handler = Proact()) File "/home/ubuntu/pysim/pySim/transport/__init__.py", line 362, in init_reader sl = ModemATCommandLink(opts, **kwargs) File "/home/ubuntu/pysim/pySim/transport/modem_atcmd.py", line 51, in __init__ self._check_echo() File "/home/ubuntu/pysim/pySim/transport/modem_atcmd.py", line 127, in _check_echo raise ReaderError('Interface \'%s\' does not respond to \'AT\' command' % self._device) pySim.exceptions.ReaderError: Interface '/dev/ttyUSB2' does not respond to 'AT' command (venv) root@ubuntu-HP-Notebook:/home/ubuntu/pysim# I tried increasing the timeout in send_at_cmd() to 1 second and 2 seconds, but i get the same result.
