I asked the seller if they could tell me the Ki and explained why I needed this, and the response I got was: "the test card is mainly test 2GB network singinal" :o) The baseband VTY show subscriber command gave me the IMSI (001010123456789) and by reading the OpenBSC code I found that for XOR I just needed the first 4 bytes of Ki, which worked out to be 1 154 2 173 (to make things easy I set the tester to use 255 255 255 255 ... for RAND). I'm not sure how I would ascertain Ki in its entirety, but maybe I don't need this anyway. Thank you for your help! Best, Andrew -- Andrew Back http://carrierdetect.com
