Thanks Domonkos.

Programming ...


Card programming failed with an execption:

---------------------8<---------------------

Traceback (most recent call last):

  File "./pySim-prog.py", line 719, in <module>

    rc = process_card(opts, first, card_handler)

  File "./pySim-prog.py", line 671, in process_card

    card.program(cp)

  File "/home/support/pysim/pySim/cards.py", line 713, in program

    self._scc.verify_chv(0x0A, h2b(p['pin_adm']))

  File "/home/support/pysim/pySim/commands.py", line 206, in verify_chv

    return self._tp.send_apdu_checksw(self.cla_byte + '2000' + ('%02X' %
chv_no) + '08' + fc)

  File "/home/support/pysim/pySim/transport/__init__.py", line 104, in
send_apdu_checksw

    raise RuntimeError("SW match failed! Expected %s and got %s." %
(sw.lower(), rv[1]))

RuntimeError: SW match failed! Expected 9000 and got 63c8.


I'm flashing this SIM card for a 5G project at
https://github.com/free5gc/free5gc


Does this SIM card SW supports 5G?


Thanks.


Br,

Chunlin
