How to Disable Mobile Broadband Menu Option in Ubuntu 22.04

Last updated: May 5, 2024 — Leave a comment

This simple tutorial shows how to get rid of the “Mobile Broadband” menu option from the upper right system status menu in GNOME Desktop.

GNOME, the default desktop in Ubuntu and Fedora Workstation, has built-in support for mobile broadband. If your computer (usually laptop) has a built-in SIM card slot, then it will show you the “Mobile Network” page in Settings and “Mobile Broadband” option in upper right menu.

For those who rarely use this feature, the option is useless but makes the menu longer. So, it’s a good choice to completely disable it!
