Modem Manager GUI
You can also use the application modem-manager-gui
- In addition to Display Bandwidth and SMS, it also can send USSD.
- It also can manage the processes that use bandwidth (Stop or Start)
But it is only available in Ubuntu Software Center for Ubuntu 12.04, Ubuntu 13.10 and above.
Ubuntu 12.10 and 13.04 users can use the official PPA. It's recommended for 12.04LTS users too to use the PPA, as the package in Ubuntu 12.04LTS repository is very old. To add the PPA, run these commands in terminal:
sudo add-apt-repository ppa:linuxonly/modem+manager+gui
sudo apt-get update
Click here to install modem-manager-gui
Also can be installed with :
sudo apt-get install modemmanager modem-manager-gui
