Mobile app hangs depending on SIM

Hello list, I'm playing with the mobile application of OsmocomBB. I have two SIM cards of two different operators. Everything works fine with one of them, as you can see in the mobile_ok log, but it doesn't with the other one, as you can see in the mobile_ko and layer1_ko log. Layer1 hangs there: SIM Request (5): a0 b0 00 00 f6 and mobile hangs there: <000f> sim.c:1065 selected file (len 246) <000f> sim.c:277 READ BINARY (offset=0 len=246) <000f> sim.c:187 sending APDU (class 0xa0, ins 0xb0) Then nothing happens. Also, when using the command "off", everything shuts down with the first SIM, but I have to use ctrl-c for the second one after mobile hangs here: <000f> sim.c:1234 exit SIM client I have the last versions of libosmocore and osmocom-bb in the master branch, and I enabled TX support. I also tried to set my IMEI in the mobile.cfg file but this does not change anything. The config file is joined as well. Did I forget something? Do you have an idea? Thank you!
