Bug description:
  I have a 3G BroadBand modem from the Portuguese TMN.
  Ref: http://tinyurl.com/7v6yvh9
   
  Its modem type is ZTE MF190J.

  I need to use it in my Ubuntu 12.04 laptop.

  I have created a definition in the "Mobile Broadband". The definition
  is done by a wizard where I select "Portugal" and  "TMN" and where I
  enter a PIN-code. Please see the picture.

  The pen indicates a green light, but still, I cannot access the
  internet. And the network-applet icon switches off.

  The config looks like this

  and

  One thing I noticed that Ubuntu first thinks that this USB-pin is a
  storage device (like a cdrom) and it mounts it to /media/ZTEMODEM.  I
  have to "Eject" this mount point first, then Linux seemingly continues
  to load the driver. The light on the USB-pin turns red, then after 5
  secs to green. The network applet says "Registered to your home
  network", then immediate after that "Modem network.. disconnected".

  I know there is usb-modeswitch commmands that can disable the auto-
  mounting.

  I have tested this same USB-pin (3G modem) on Windows and it work perfectly well.
  I also used its Windows application to disabled the PIN code (just for testing).
