Programming SIM card RAND?

Hi,

you can read the IMSI in the EF_IMSI file on the SIM card.
tools (like softSIM and others) are available to read that out for you.
Ki is not readable on normal SIM cards. If it's a developer SIM, then you have to look in your SIMs manufacturer manual/specification.
If it's a MagicCard, GreenCard, or SysmoSIM, you should be able to overwrite them using pySim-prog.py.
