laforge has submitted this change. ( https://gerrit.osmocom.org/c/pysim/+/31813 ) Change subject: fix SimCardCommands.run_gsm(): always use CLA=0xa0 ...................................................................... fix SimCardCommands.run_gsm(): always use CLA=0xa0 Depending on the card type (SIM or USIM/ISUM), self.cla_byte may be either 0xa0 or 0x00. Sending RUN GSM ALGORITHM with CLA=0x00 fails with SW=6985 (Command not allowed), so let's make sure that we always use CLA=0xa0 regardless of the card type.
