Hi Paul, I'm fighting a similar problem while using the current development branch of OsmocomBB. Trying to connect to both OpenBSC and OpenBTS using the test SIM that's available in OsmocomBB. I have a Motorola C123. Is this feature supposed to be fully functional at the moment? Before trying to associate, I switched the mobile to the network-select-mode: manual. The latest behavior is that it's not possible to connect to OpenBSC with the following output from the "mobile" OsmocomBB app: OsmocomBB# show cell 1 ARFCN |MCC |MNC |LAC |cell ID|forb.LA|prio |min-db |max-pwr|rx-lev -------+-------+-------+-------+-------+-------+-------+-------+-------+------- 514DCS|230 |10 |0x04b9 |0x0ba8 |no |normal |-110 | 0 |-51 571DCS|230 |09 |0x2058 |0x69d7 |no |normal |-105 | 5 |-66 648DCS|230 |01 |0x6050 |0x3571 |no |normal |-105 | 0 |-69 777DCS|230 |03 |0x1f5e |0x2aba |no |normal |-105 | 0 |-87 OsmocomBB# network select 1 230 10 Network not in list!

Hi Peter and others, Yes, I had enabled the software sim before trying to associate with the BTS. I also defined my IMSI and rebooted the phone afterwards. Maybe, I'd like the people here to answer these questions for me, if possible: Is the "test sim/soft sim/testcard" feature fully functional in the current release of OsmocomBB? (I want to try couple scenarios with a OpenBSC test setup that another student has been running at our faculty. I'm setting up a OpenBTS/USRP scenario too.) Is the sim reader feature in the "mobile" app currently able to work with HW sim cards? (I want to try running the FOSS firmware as a normal phone for a bit.) If my Motorola C123 is sim-locked to some German service provider, do I have to find ways to unlock it to be able to run a Czech sim card or does the OsmocomBB firmware override the sim lock by default? I think I was unsuccessful last time I tried popping one in and enabling it through "OsmocomBB mobile". I can provide more info after I've re-tried this. I hope my questions stick to the spirit of this list well enough, if not, please let me know. Thanks, Martin Dne 13.2.2012 18:22, Peter Stuge napsal(a):
