It looks to me like you just need to get the settings figured out to get
the modem to connect, and the modem itself is already working.  Like I
mentioned previously, every time I've used my phone as a modem, I just use
a dialer like KPPP and dial #777 as the access number.  I use Sprint
though, so the settings that you would use are probably different.

This page here may be of some assistance:

It looks like Telstra uses *99# as its access number and telstra.internet
as its apn which some networks require.

What version of Fedora/Linux are you running?  I have a Fedora 15 box here
with a HUWEI modem (no sim card though), and it seems pretty
straight-forward to get it to connect.  In Network Connections, there is a
Mobile Broadband tab.  If you click Add, it launches a wizard to add a new
connection.  It will first ask you which modem/connection device to use,
the next screen will prompt you for the region, the next screen will prompt
you for a carrier, or you can enter one manually.  The final screen shows
you all 3 selections that you just made.  When you click apply, it will
prompt you to enter a connection name, and update the Number, username, and
password.

When you have that done, you just select the connection from Network
Manager to connect.  With the hardware I have on hand here, I can see that
the modem is attempting to connect to the network, but as I don't have a
SIM card in this modem (it is for international travel), it doesn't
actually connect.

I hope this is helpful.
