I have a problem with the WWAN (Qualcomm Gobi 2000) in my Lenovo ThinkPad W510. I can not unlock my SIM card with the correct PIN. I enter the PIN in this dialog and after this SIM PIN

I get immediately this dialog

SIM PIN2

After I enter the SIM PIN2 the only thing that happens is that I get a notification that says that the connection is disabled.

I know that this is not a problem with the PIN or the SIM card because I checked both with my Windows 8 notebook.

What I have to do to use the WWAN in my notebook.

Just found this via journalctl

What happens after you type PIN2-code? The second dialog doesn't seem to be the same as the first dialog. It is asking for PIN2. –  Ramesh Apr 28 '14 at 21:01
    
@Ramesh I get a notification that says that the connection is disabled. Nothing more. –  Marcel Janus Apr 29 '14 at 4:29

I've never used one of these modems but am interested in trying to help solve your issue. I found this thread which discusses the use of a command line tool called mmcli. The thread is called: Re: Sierra Wireless MC8355 - Gobi 3000 with AT&T. This seemed related since there were a number of mentions of a tool called mmcli.

The Chromium project alos has this page which shows how to use it to debug a cellular modem connection, titled: Modem debugging with mmcli (from the modemmanager-next package).

  • Listing modems/finding the index number of a modem (The modem index frequently changes during a suspend-resume cycle):

    $ mmcli -L
    

    (Further examples will assume modem index 0. Substitute your own modem index where necessary.)

  • See the status of a modem:

    $ mmcli -m 0
    
  • Enable a modem (useful side effects usually include registering on a network and getting an operator ID and name)

    $ mmcli -m 0 -e
    
  • Minimal connection and disconnection:

    $ mmcli -m 0 --simple-connect="apn=foo.carrier.com"
    $ mmcli -m 0 --simple-disconnect
    
  • Set logging level to maximium (equivalent to the old mm_debug debug):

    $ mmcli -G DEBUG
    
  • Set logging level to minimum (equivalent to the old mm_debug err):

    $ mmcli -G ERR
    
  • Arbitrary AT commands - available if ModemManager is started with the --debug flag:

  • This is a good test command to see if ModemManager is speaking to the modem. The modem should already be in state E0 (no command echo); you should immediately get an empty reply. You can check /var/log/messages for the message exchange if you've previously turned up the logging level to maximum.

    $ mmcli -m 0 --command="E0" 
    
  • Do a network scan and list the carriers found - this requires a longer-than-default timeout.

    $ mmcli -m 0 --command-timeout=120 --command="+COPS?" 
    

I believe this tool is included in the package ModemManager.

If I try to enable the modem I get: mmcli -m 0 -e error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.libqmi.Error.Protocol.InvalidTransaction: Couldn't set operating mode: QMI protocol error (60): 'InvalidTransaction'' –  Marcel Janus May 10 '14 at 9:34
  1. PIN2 issue:

A lot of QMI modems I've played with will ask for PIN2 after having unlocked PIN1. When the modem asks for PIN2 you can anyway launch a connection to it. PIN2 doesn't prevent you from getting connected.

In other words, the UI should not keep asking for PIN2 once PIN has been entered: even if ModemManager says "UnlockRequired"==PIN2, the State in ModemManager will no longer be "Locked". Please report a bug to KDE, which is the one I think doing that logic.

2. Invalid transaction in QMI

Regarding the Invalid Transaction... that should not happen :) If you keep getting these errors, please try to gather ModemManager debug logs following these steps. Basically, libqmi will try to match the requests you send with the responses you get; and getting back a mismatched transaction will trigger that error. If you do get the debug logs, please post them to the ModemManager mailing list or to the ModemManager bugzilla.

You can try to disable the PIN2 lock on the SIM card with qmicli:

sudo apt-get install libqmi-utils
sudo qmicli -d /dev/cdc-wdm0 --dms-uim-get-pin-status
sudo qmicli -d /dev/cdc-wdm0 --dms-uim-set-pin-protection=PIN2,disable,0000
sudo qmicli -d /dev/cdc-wdm0 --dms-uim-get-pin-status

This assumes that 0000 is your current PIN2 – adapt as needed.

However, some mobile network operators produce SIM cards where PIN2 cannot be disabled. In that case, you would get something like:

error: couldn't set PIN protection: QMI protocol error (3): 'Internal'

(This was with qmicli 1.10.2.) In normal use, it would make no difference if PIN2 can be disabled or not: PIN2 is only used for FDN (Fixed Dialling Numbers), and diabling the FDN feature would also mean that PIN2 is never asked for. Except if software has an issue, like in this case … . As a workaround, you might try PIN2 verification via qmicli, and have that command executed at system start automatically:

sudo qmicli -d /dev/cdc-wdm0 --dms-uim-verify-pin=PIN2,0000
