So am I right in concluding that the SIM has a PIN associated with it and I’m not sending the correct one (from the code it looks like it’s sending “DDDDDDDD” as the default since I’m not specifying it in the command line)?

I also tried some of the other branches, as people on other forums had reported better luck with those, but I get the same error. Is there any documentation explaining the magic byte values that are sent back and forth to the card? I'm having a hard time understanding the spec by which the program is trying too communicate with the card. Any help is greatly appreciated. Thanks, Billy
