Micro Sim-card Mobile broadband problem

I've checked that the mobile broband is enabled, i've tried making a connection for the sim-card. -there is a dialog box asking for device and its just empty.

What is the output of:

lsb_release -a; uname -a; lsusb

Thanks

Thank you.

And there is a micro simcard reader on the side next to the Ethernet connection, and inside a Telenor Sim-card. And I've tested the simcards function.

What output do you get for the commands

sudo lshw -short
sudo lshw -C network

Maybe also http://askubuntu.com/questions/747959/sierra-e7455-mobile-broadband-modem helps

sudo lshw -short.

This is the micro sim?

I will try in the morning, with the wiki link.

What is the output of

apt-get install libqmi-utils.

This ruleset was modified to match Sierra E7455 modem. Add the following content to a new udev file, e.g. /etc/udev/rules.d/99-sierra.rules.

After adding these rules, you should reboot your system! Finally the Ubuntu Network-Manager should recognize the device!

And make sure to add a valid SIM-Card – otherwise the CDC Device will be recognized as “unavailable”.

So, tried the wiki link.

Now the enable mobile broadband is gone from the network tab.
only enable Wifi and enable Networking is there.

Reading all the details of the document on askubuntu and the links from there, it seems that the instructions should work for a Sierra Wireless EM7455, but they apparently do not work on a Lenovo T460s.

From what I can see on https://lists.freedesktop.org/archives/libmbim-devel/ , there are people working on the mbim and qmi programs to cope with the problem. Maybe someone will come up with a solution in due course.
