Since there is no official download link for the software I recommend you search in Google and download the software.
Once you download the package please use the following commands to install and run the software.
Open a terminal and type the following commands:
sudo bash /"path where you extract mobile partner"/Linux/install
//note: If you are already logged in as root, delete SUDO as you already have access to system files.
When the installation is finished, plug-in your USB modem and use it accordingly.
