When I am using C app that is using ModemManager library and when I extract status of SIM PIN, I am getting that SIM requires PIN2 (MM_MODEM_LOCK_SIM_PIN2), but when I send AT command I am getting that SIM is READY, that means that SIM is unlocked. SIM is connected correctly, but it seems only that message is wrong. After calling test app: <img style="width:5.875in;height:2.677in" id="Picture_x0020_1" src="cid:part1.PI9NtA3d.0xkY8Zw3@semex-engcon.com" class="" width="564" height="257"><o:p></o:p> After calling AT command: <img style="width:2.4583in;height:1.0in" id="Picture_x0020_2" src="cid:part2.aRPOWFaZ.jEJ0AkIG@semex-engcon.com" class="" width="236" height="96"> I am getting correct PIN status messages if SIM requires PIN or PUK, I tested it, but when I send correct PIN, SIM connects, but PIN status message is that SIM requires PIN2.
