Hello Silvain, please find attached a patch for pySIM which I put together today after some work to get the extra parameters which I needed on the sysmoUSIM-GR1. Don't know if it only works for those cards. This fixes some bugs in setting the IMSI and also adds support for selecting USIM and writing binary/records in there. I have also added some parameters like MSISDN or the forbidden MCC to black-list other national networks, in the idea that one would provision on the test 001/01 network. The data formats are not so well defined or clean as I was on a get-it-done schedule and did not actually read the specs. Anyway, the result works fine for me. Otherwise I could only use pySIM with the GemPC Express reader. I read that you have a PC Twin Reader which seems to be more common, but I am getting the following with that, so any help would be appreciated: Programming ... Traceback (most recent call last): File "./pySim-prog.py", line 544, in <module> card.program(cp) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/cards.py", line 364, in program data, sw = self._scc._tp.send_apdu_checksw("0099000033" + par) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/transport/__init__.py", line 88, in send_apdu_checksw rv = self.send_apdu(pdu) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/transport/__init__.py", line 69, in send_apdu data, sw = self.send_apdu_raw(pdu) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/transport/pcsc.py", line 75, in send_apdu_raw data, sw1, sw2 = self._con.transmit(apdu) File "/usr/lib/python2.7/dist-packages/smartcard/CardConnectionDecorator.py", line 82, in transmit return self.component.transmit(bytes, protocol) File "/usr/lib/python2.7/dist-packages/smartcard/CardConnection.py", line 140, in transmit data, sw1, sw2 = self.doTransmit(bytes, protocol) File "/usr/lib/python2.7/dist-packages/smartcard/pcsc/PCSCCardConnection.py", line 175, in doTransmit raise CardConnectionException('Failed to transmit with protocol ' + dictProtocolHeader[pcscprotocolheader] + '. ' + SCardGetErrorMessage(hresult)) smartcard.Exceptions.CardConnectionException: Failed to transmit with protocol T0. Transaction failed. P.S. I must apologize if the patch is crappy, as I could not yet be bothered to read a book or something on python. Cheers, -Dragos -- ----------------------------------------- Dipl. Eng.
