I have only tried the out of the box sim cloning. Still cannot understand hwo the clones work. Hope that anyone could explain a little bit. I guess quite a lot of people want to know.

For example, a silver card (16F876 + 24LC64), the 16F876 is the microcontroller and the 24LC64 is the eprom.

1) When we are reading the codes "Ki" and IMSI with reader. Where are they stored, they should be stored in the 24LC64, right(well, you cannot read KI directly off the prom)?
2) Is there any program stored in 16F876?
3) Is the program read out too?
4) When the KI and IMSI are found. How can they be written into another blank SIM card?
5) Does the blank SIM card need formatted or initialized first?
6) When the copied program to be written into the 16F876 of another blank sim card?

Sorry too many questions.
