Can we reprogramm original SIM?

[quan]

Hi all!
How can we know what kind of processor and eeprom in original card? and if can, can we reuse/reprogram that card for another purpose (not gsm) ?. Thanks 4 reading this thread.

if you checked the post a few posts back then you will notice that sim cards are not rewritable, there is protection on the chip.

Not so sure about the types of the pic and eeprom tho.

so how about blank card ? , ex: we use a silver card to clone a original SIM, and then we reprogram it to clone another SIM or use 4 another purpose.Thanks .

Yes, if you program a silver(or and blank card, but not an original card) card and then you decide you want to program it again then you can.

Silver cards can be programmed as much times as you like, for any amound of cloned cards.

Thank you Blootoon. I'm new , so may be i have some silly question( or FAQ),so plz don't laugh if i'm wrong.
I want to ask that, i have a original SIM, i've already know Ki and IMSI of it (by Phoenix schematic and cardinal68).
Now, i want to clone it, so what program i should use and what schematic use with it. U know, i cant buy any device because in my country, they dont sell it, so i have to do it myself.
Thanks to anyone who read this thread , n if u reply==>thanks very very much.
