Answer 2

V Mobile Broadband

V Mobile Broadband is the original Vodafone Mobile Connect software for Linux rewritten to be compatible with Network Manager. Vodafone is a distributer of Huawei USB modems. V Mobile Broadband is developed by Vodafone's open source Betavine Connection Manager team. For the latest developments, check out their Launchpad Page and GitHub Page

V-Mobile-Broadband is mentioned as having these functionalities:
⠀• Connection & Disconnection
⠀• SMS
⠀• Display Bandwidth
⠀• Display Data Usage

Unfortunately, V Mobile Broadband is not available in Ubuntu Software Center yet. You'll have to install it from PPA. To add the PPA, run these commands in terminal:

sudo add-apt-repository ppa:crass/v-mobile-broadband
sudo apt-get update

After successfully adding the PPA, click here to install v-mobile-broadband
Or, run the following command:

sudo apt-get install v-mobile-broadband

Warning: v-mobile-broadband depends on wader, which replaces Ubuntu's default modemmanager. So, if you encounter any problem with the new setup and decide to uninstall v-mobile-broadband, don't forget to reinstall modemmanager package.
