Hi Team,
I am getting the following error while running the pySim-read.py , This
program runs fine on old SIM cards but in new SIM cards it gives the below
error.
I did a comparison of directories on both the SIM cards and there is a
difference, Kindly guide how to fix it . Although EF.ICCID exists in both
the SIM cards .
Additionally pySim-shell.py works well .
python3 pySim-read.py -p 1

Good afternoon,
I am trying to verify the CHV2 verification on an Amarisoft Test SIM Card. With a HID OMNIKEY 3121.
I have issues with the CHV2 verification with the pySim software and amarisoft simcard.
I get the error below.
Can you please give me some hints on how to fix this issue as I have no idea of how to start.
Sincerely,
Valentin M.

Dear Engineer,
I have a few questions regarding simtrace2-cardem-pcsc that I would like to consult with you:
(1)、I am using simtrace2-cardem-pcsc to access a remote SIM card by connecting the SIMtrace2 board to a mobile terminal. When I use pcsc_scan, it shows that the card reader has opened the SIM card successfully, and the other end is also connected to the SIMtrace2 board correctly. However, there are no valid APDU commands being printed. Through simtrace2-tool, I only see some reset information.
(2)、I would like to connect the SIMTrace2 board to the soft SIM on my computer. Is there any related manual or documentation that could guide me through this process?
I would greatly appreciate any advice you can provide when you have time.
Thank you very much.
Best regards,
Peitao Jia

Hello,
I am trying to update EF.EHPLMN with around 20 PLMNs.
With edit_binary_decoded, I am able to add them successfully.
But I am trying to update them directly using update_binary_decoded command from from the pySim-shell prompt. But I am not working.
It would be really helpful if somebody could help me with it.
Below is the full list of commands that I tried.
Welcome to pySim-shell!

Hello,
I am having difficulty with a particular SIM card over osmo-remsim. On the bank daemon side, PCSC is timing out after 1 second on the same transaction (modemToCard: 81f2400202) after every reset. This behavior is very reliable and happens on every reset/initialization sequence from the modem. When I enable PCSC debugging, I see it is getting back the error CCID error 0xFE “Card absent or mute” from the CCID reader. When I use this card directly attached to the modem, everything is fine and the modem can go online (but I have no insight as to whether the modem is encountering an issue with the same APDU, or not).f
When this transaction error occurs, osmo-remsim-bankd closes the connection, leading to a removal/insertion and card reset event. So, the system is in infinite loop of resetting the card, making a bunch of successful APDU transactions, timing out on the offending transaction, and then resetting again all over again...
As an experiment, I changed osmo-remsim-bankd behavior to ignore the PCSC error, leave the connection open, and return a general error (0x6F 0x00) to the modem. When I do that, the modem periodically re-sends the offending APDU every few seconds, but, despite that, everything else is fine and the modem can now go online with this card over osmo-remsim. I’m thinking either card needs more time to answer this query, or perhaps it does not support this query at all.
Based on some earlier troubleshooting it appears to be related to eSIM (eUICC) functionality. This particular card reports as an eSIM (side note: curiously, its EID is blank). When I use old modem firmware that does not support eSIM capabilities, the card works just fine over osmo-remsim. It is only when I upgrade the modem firmware to a version that supports eSIM that this problem appears.
Other things I tried:
- Upgrading to latest libccid and pcsc-lite — no change
- Using a different card reader with different chip set — no change, and both are listed as “should be supported” by pcsc-lite.
A couple questions:
- Is there a way to change the timeout? I tried modifying libccid to set bBWI to 0xFF for this transaction (it was 0x00), but that had to effect. Internal timeouts within pcscd seem to be set to 3 seconds, and so I do not think they are coming into play, here.
- What are your feelings on having osmo-remsim-bankd ignore this error and return a 0x6f 0x00?
- Any other ideas?
Here is the truncated log of traffic leading up to the offending APDU:

Hello,
Here is a patch for handling malformed IMSI
If you misswrited your IMSI, it will be impossible to read or edit it again :(
This patch fix that
Thanks
Goodbye
Dear osmocom developpers,
This is just to let you know that the Python library pycrate has a new home
: https://github.com/pycrate-org/pycrate. The packages on Pypi are now
feeded from there. This library can be used in many cases dealing with
mobile signalling.
I wanted to let you know, as even if I am not aware of any osmocom projects
depending on it, some of you may use the library from time to time, or
could have local applications depending on it.
Best Regards
Benoit
Hi all,
behind the scenes, a team at sysmocom[1] has been helping IoT MVNO
onomondo[2] implementing a pure software implementation of the GSM SIM /
ETSI UICC / 3GPP USIM.
The resulting software has now finally been released in the
onomondo-uicc (see https://github.com/onomondo/onomondo-uicc)
The implementation covers a rather feature-complete implementation of
the file system (including access rules / permission model, PIN
authentication), authentication (MILENAGE), and even OTA RFM (remote
file management).
You can run the code either in software (and access it via the vpcd
ifd_handler to make it appear via PC/SC) or you can run it behind a
SIMtrace2 in cardem mode. Or you could cross-compile the library to run
on a microcontroller (assuming it has a ISO 7816 card-side UART) or
directly within a cellular modem/baseband.
Of course, beyond research this is only useful in situations where you
are the operator (like in a private network) and hence know the K/OPc
key material that allows you access to the cellular network.
There is some overlap to the parallel work of Tomasz Lisowski's swsim[3]
- sadly we were not in a position to release the onomondo-uicc code back
then, so the duplication of effort could not be avoided.
Regards,
Harald

[*] this is how we started to call the "unstructured" part of osmocom
developer conferences in the past, basically where anyone can talk about
anything, no formal schedule or structure.

Hi all!
[cross-post to make sure everyone knows about it, please follow-up-to
the osmodevcon(a)lists.osmocom.org mailing list for further discussion]
As I mentioned several times at different occasions, I really think we
should put together a OsmoDevCon again. In case you don't know what that
is, please see https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon
We should have restarted already in 2023, but I really was too busy and
it was a somewhat difficult year for me at times, sorry.
Date
----
In terms of timing, I am thinking about "after April but before the main
summer holiday season (June-August)". That leaves May.
Given that May has the whitsunday weekend as well as GPN
(Gulaschprogrammiernacht, a CCC event that will likely conflict
of interest with some people interested at attending OsmoDevCon), I'm
currently considering the following candidate dates:
* May 3 to 6
* May 24 to 27
This is as usual a friday-to-monday timeframe, allowing people who don't
work professionally on osmocom to attend just the two weekendd days,
while others can attend the full 4 days.
Venue
-----
In terms of venue, I'm hoping we can move to a slightly different
arrangement where the whole group stays together for the whole duration
of the event - as opposed to everyone staying at different hotels and
having to commute from hotel to venue and back every day. So something
like a hotel with a sufficiently large meeting room, hotels and catering
all day. And all of that ideally at a nice venue with some kind of park /
outdoor area, not downtown at the city center. Yes, that will obviously
come at a higher price tag than we're used to - but I'm confident we can
get that covered between sponsors and sysmocom.
Do you guys think this is a good idea? Or would you prefer the
traditional ad-hoc approach at IN-Berlin?
Regards,
Harald
