Hi List,
When using MITM it is possible to set the SIMtrace<->phone voltage levels using ATR, giving a clear-cut way to solve the incorrect I/O level problem:
See byte TA(3) C7->C2
orig ATR from card: http://smartcard-atr.appspot.com/parse?ATR=3B9F95801FC78031E073FE2113574A330...
modded to select only 3V: http://smartcard-atr.appspot.com/parse?ATR=3B9F95801FC28031E073FE2113574A330...
Cheers, Tom
