What happens if you just run AT+CPIN? before trying to get the ICCID? Still returns error? I'm not sure if it makes sense to only be able to load ICCID once a PIN failure has happened. Maybe the SIM card needs more time to get initialized or something. -- Aleksander _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
