Billy Jones wljones at praxiseng.comI have two SIM card I inheritted from a previous project that I've been told came from the same vendor. When I run `pcsc_scan` on them, I get the following output for both:
Reader 0: OMNIKEY CardMan (076B:3022) 3021 00 00
Card state: Card inserted,
ATR: 3B 7D 94 00 00 55 55 53 0A 74 86 93 0B 24 7C 4D 54 68
ATR: 3B 7D 94 00 00 55 55 53 0A 74 86 93 0B 24 7C 4D 54 68
+ TS = 3B --> Direct Convention
+ T0 = 7D, Y(1): 0111, K: 13 (historical bytes)
TA(1) = 94 --> Fi=512, Di=8, 64 cycles/ETU
62500 bits/s at 4 MHz, fMax for Fi = 5 MHz => 78125 bits/s
TB(1) = 00 --> VPP is not electrically connected
TC(1) = 00 --> Extra guard time: 0
+ Historical bytes: 55 55 53 0A 74 86 93 0B 24 7C 4D 54 68
Category indicator byte: 55 (proprietary format)
Possibly identified card (using /usr/share/pcsc/smartcard_list.txt):
3B 7D 94 00 00 55 55 53 0A 74 86 93 0B 24 7C 4D 54 68
SIM from sysmocom sysmoSIM-GR2
When I try to program one of the SIMs, it works fine:
$ sudo ./pySim-prog.py -p 0 -i 001010000000001 -k ffffffffffffffffffffffffffffffff -t sysmoSIM-GR2 --num=1 --mcc=001 --mnc=01
Insert card now (or CTRL-C to cancel)
Generated card parameters :
> Name : Magic
> SMSP : e1ffffffffffffffffffffffff0581005155f5ffffffffffff000000
> ICCID : 8901001010000000017
> MCC/MNC : 1/1
> IMSI : 001010000000001
> Ki : ffffffffffffffffffffffffffffffff
> OPC : f134b55cea2942ebbd213c82e084be62
> ACC : None
Programming ...
Done !
But on the other I get:
$ sudo ./pySim-prog.py -p 0 -i 001010000000001 -k ffffffffffffffffffffffffffffffff -t sysmoSIM-GR2 --num=1 --mcc=001 --mnc=01
Insert card now (or CTRL-C to cancel)

RuntimeError: SW match failed ! Expected 9000 and got 9840.
I also tried some of the other branches, as people on other forums had reported better luck with those, but I get the same error. Is there any documentation explaining the magic byte values that are sent back and forth to the card? I'm having a hard time understanding the spec by which the program is trying too communicate with the card.
Any help is greatly appreciated.
Thanks,
Billy
