Before proceed with oscilloscope, I do a last test using simtrace and a Samsung Galaxy S3 with this UICC and surprisingly it works, so I have the ATR APDU: 3b 9f 96 c0 0a 3f c7 a0 80 31 e0 73 fe 21 1b 65 d0 01 74 0e a1 81 0f 9c

From there; Fi=512, Di=32, Protocol T=0, class accepted by the card: A, B and C (https://smartcard-atr.appspot.com/parse?ATR=3b9f96c00a3fc7a08031e073fe211b65d001740ea1810f9c)

After this, I test over and over again with the same UICC card and an iPhone6 but never got ATR response, just got "ATR APDU: " and iPhone don't recognize SIM card. SCR3310 reader never recognizes the card, always "Card state: Card inserted, Unresponsive card" response.

I test simtrace/iPhone6 and SCR reader using same UICC type from other operator with same results (but working with simtrace/S.Galaxy S3)

I think the best way to analyze this is to understand the exact voltage,
clock rate and Fi/Di values your card is operating on on the working
reader(s). Most likely at least one of the parameters is different on
the non-working readers.

You should be able to figure all the related values out if you talk
CCID directly to the USB device, or extend / "hack up" the ccid driver
you're using. Alternatively, an oscilloscopse should also be able to
tell you related information.

Regards,
Harald
