This has been tested on Debian 9/Stretch but it should work on any Debian based version of Linux (Ubuntu, Debian(duh), Mint, Kali ect.)

Download the firmware that matches the carrier type you plan to use:

Open a Terminal and run all of the following commands with Sudo privileges

navigate to "/lib/firmware" by running "cd /lib/firmware then "sudo mkdir gobi" then cd into Gobi
Run: "tar xvf ~/path/to/gobifirmware.tar.gz"
Run: "sudo aptitude install gobi-loader modemmanager" to install the Gobi Modem Manager
Run: "cp /lib/udev/rules.d/60-gobi-loader.rules /etc/udev/rules.d/60-gobi-loader.rules" to move the gobi rules file into the proper location
Run: "sudo nano /etc/udev/rules.d/60-gobi.rules" to edit the rules file
replace the file contense with the info here: whitch adds the CR-48 Gobi HWID
Run "sudo pkill modem-manager; sudo rmmod qcserial; sudo modprobe qcserial" to refresh the modem firmware


Open your Desktops Modem Manager and you should now be able to add a mobile broadband connection! Enjoy 3G!
