Fedora 20 dosen't accept correct PIN for mobile broadband

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 I get immediately this dialog 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.
