Second try. (I already sent this mail yesterday, but it did not appear in the mailinglist. I do not know why. Maybe because I attached a file (a patch))
Hi all,
This is my first post to the OpenBSC mailinglist.
I had a problem with the latest pysim version giving errors while trying to program 2G (Fake)MagicSIM cards. This had worked fine in the past with an older release from 2011. I tried al lot of versions in between. I was finally able to narrow it down to the commit that broke compatibility with (fake)magicsim:
http://cgit.osmocom.org/pysim/commit/pySim/commands.py?id=8c1b33c439fef423c3...
The comment with this comit is: "Do not return the FCI information while selecting a file The sysmoUSIM-SJS1 card does not support returning the FCI information. Plus, the FCI information are not used anyway."
If I revert the change with attached patch, it works again.
But it may break sysmoUSIM-SJS1 compatibility. I am not sure on how to test whether the programming of sysmoUSIM-SJS1 still works fine and if the SIMS themselves then will still work as expected with OpenBSC or OpenBTS or OpenAirinterface.
If the code needs to stay in for sysmoUSIM-SJS1 then we probably need somehing like the pseudocode below:
if carttype is fakemagicsim: "a4000002" elif cardtype is sysmoUSIM-SJS1: "a4000C02" else: #What should be the default for the other cards?
Or is there another solution?
With best regards,
Martin Dudok van Heel

Hello,
Hi!
I’m still having problems, sorry to report this. Below the log file of different combinations:
I’ve used different (same model) SIM cards. I’ve reinstated the USB reader. Tried in different USB ports. No Luck.
What am I doing wrong, can you please help?
Sysmocom sold the last 16in1 magicsim in 2012? Did you buy these cards from us? Maybe this specific one is just broken? Maybe try an older version of pySIM? E.g. maybe some of the patches required for the sysmoUSIM-SJS1 broke magicsim support?
In the future you could consider getting the sysmoUSIM-SJS1 from us, they are of way higher quality than the Chinese (GRcard, magicsim, etc.) ones. For emergencies like these it might make sense for you to get a support contract from sysmocom as well.
good luck
