Hi Gentleman,

To change the IMSI of original card, is the same that this answer:

Normaly the IMSI file inthe SIM (7F20:6F07) are protected with a administrative PIN (normaly PIN4)... If you have this PIN.. you can change the IMSI.

The Ki is other problem. This number probably are in ROM and the SIM haven´t gont any protocol to change...

Best regards,
Sir Graham.
