Hi Team, I am getting the following error while running the pySim-read.py , This program runs fine on old SIM cards but in new SIM cards it gives the below error. I did a comparison of directories on both the SIM cards and there is a difference, Kindly guide how to fix it . Although EF.ICCID exists in both the SIM cards . Additionally pySim-shell.py works well . python3 pySim-read.py -p 1 Using reader PCSC[HID Global OMNIKEY 3x21 Smart Card Reader [OMNIKEY 3x21 Smart Card Reader] 01 00] Reading ...
