For the IMSI you can read the appropriate EF of the SIM (the phone does the same to get the IMSI). Ki usually cannot be read back but because A3/A8 for a Test SIM is GSM XOR you can calculate Ki from the SIM response to the RUN GSM ALGORITHM command. OpenBSC contains code for the GSM XOR algorithm, this should give enough hints for how the calculation is done. For setting IMSI and Ki you most certainly have to contact the seller of the SIM card and hope that he can/will tell you the details.
