Does anyone knows if the phonebook on the chip GSM SIM CARD is encrypted? I need to make a READER/WRITER for these cards and i need to know how to access the phonebook data. Is it easy? Is there some algorithm that encrypt this kind of data? I found on internet a circuit that reads and writes from/on the chip, but its not enough, i need to know how to access the data.
Maybe there's a hardware protection, i don't know. Maybe the PIN number or PUK are necessary? If i use the Serial port to read the data, what kind of thing do u thing will come from there? and i dont know i i'll need to convert to ASCII. I am completly lost.
Can anyone help me?
