Thanks.

Try to seek within SIM Application Toolkit information. ISO 7816, GSM 11.11, GSM 11.14 standards also.
But more quick way - scan any prog for work with card reader, wich support contacts r/w function. Better UART's one, not usb. USB card-reader use own cmd, and their logs will far from understanding how SIM-card works.
