Before you can do this you should have disabled the ISO mode on the modem from the instructions here.
You can send and receive SMS using the modem that comes with Telstra prepaid mobile broadband by using a program called Phone Manager which can be installed in gnome. You can install it with
sudo apt-get install gnome-phone-manager
Once it is installed you can
n access it in Applications > System Tools > Phone Manager.
Open phone manager and its icon will appear in the notification area. Right click on the icon and go to preferences.
When you are in preferences, click on the connection tab.
Select the phone connection as ‘Other Port’ and enter the port as the port that your modem is using. It is probably ‘/dev/ttyUSB3′ but could be something else. You can use ‘ls /dev |grep ttyUSB’ to help you find the correct port. It will usually be the last one that is listed from the command.
Close the preferences window. You will now be able to send and receive SMS messages using your mobile broadband modem.
