I have a few questions regarding simtrace2-cardem-pcsc that I would like to consult with you:
(1)、I am using simtrace2-cardem-pcsc to access a remote SIM card by connecting the SIMtrace2 board to a mobile terminal. When I use pcsc_scan, it shows that the card reader has opened the SIM card successfully, and the other end is also connected to the SIMtrace2 board correctly. However, there are no valid APDU commands being printed. Through simtrace2-tool, I only see some reset information.
(2)、I would like to connect the SIMTrace2 board to the soft SIM on my computer. Is there any related manual or documentation that could guide me through this process?
My 2G phone no longer shows the “no card” message, but it still cannot make calls. Is there any further configuration needed to enable the remote SIM function?
Can the simtrace2 be used to achieve separation of the SIM card from the phone while still allowing the phone to function normally? If not, what part is missing?
Thank you very much for your help. Please reply when you have time, as I would like to learn more.
It is very strange that the communication with the SIM card now generally works, but still you say you cnanot register to the network. It should simply work.
I think it would be best if you could provide the full log file (and GSMTAP pcap file) from the moment you turn on the phone. Maybe something shows up there, whihc can help us to analyze this further.
In general, I would suggest to also try with other phones/modems or other SIM cards, so you get to at least one fully working scenario. Then we could look at differences to the non-working case.
