Dirk Kirsten dirk.kirsten at uni-konstanz.deHello, We would like to do some active manipulation between our ME and the SIM card. As I understood correctly, the hardware SIMtrace project is just about passive monitoring the traffic in between, am I right? So this seems to be inappropriate for our aims. So we thought about a solution more like the RebelSIM card, which is documented as well in the osmocomBB wiki. Unfortunately, the information given there are also very vague. So maybe it is just outdated: Does anybody worked with the RebelSIM card in a way that they try to manipulate the responses from the SIM (or do something else, except from unlocking their phone)? Is it possible to flash it via SIM card interface?! What we actually want to do is to replace same values, e.g. we want to provide another Kc than the SIM card in fact has (this is solely a research project). So maybe there is some other way to do is, except the approach based on RebelSIM? If so I would be grateful for your valuable feedback. Cheers, Dirk
