Hi Team,
I dig it further for more information and the reason I can understand may
be that post getting SW as 6e00 it runs the classical SIM procedure since
its a USIM hence the further procedure gets failed .
I captured the packets between the SIM and card reader by SIMTRACE, In
successful case it show the packets but in unsuccessful case it shows as
packet malformed ,
Packets captured which successful SIM card.

I am attaching the output of the "tree" command from both the SIM cards ,
Which I login via the pySim-shell.py program .
Could it be a case that APDU response from problematic SIM cards is
protected ?

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]
