[Ubuntu-PT 9388] Help with TMN wireless 3G modem in Portugal

[Osmo Antero]

Hello,
I have moved temporarily to Portugal and would like to have a wireless
3G-modem for my Ubuntu 12.04 laptop.

So I bought this 3G wireless USB-pen from TMN.
http://tinyurl.com/7v6yvh9

It's 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 "Connected to the home network", then immediate after
that "No wireless connection...".

I have tested this same USB-pin (3G modem) on Windows and it work perfectly
well.
I also used its Windows application to switch off the PIN code (just for
testing). I have this 3G-modem under evaluation before final registration.
I need to get Portuguese Numero Fiscal etc.

Do you know how to setup this ZTE MF 160J modem in Linux?
