Recently I bought  a Huawei U7519 phone on the Wind Mobile service. The phone tethers using Windows but what use is that to me?  Here is how I made it work using Linux.

As root:

echo "option"  >> /etc/modules

edit /etc/rc.local and add before exit 0: echo '12d1 101e' > /sys/bus/usb-serial/drivers/option1/new_id 

Download and install the software as per the instructions at this link: http://www.draisberghof.de/usb_modeswitch/

You should be able to plugin your device and will have a /dev/ttyUSB0 (which you can confirm with ls /dev/ttyU*

Now you can right click your NetworkManager in the panel and edit connections > mobile broadband > add t-mobile internet then edit that profile like so: mobile broadband > apn = internet.windmobile.ca

You can also select connect automatically on the mobile broadband tab.

Surfs up!
