I have tried Telstra and Optus 3G USB sticks and have had problems with both. I therefore recently purchased a Vodafone Mobile Broadband USB Stick (model K3765 and made by Huawei). I followed the instructions about installing the software however I kept getting an error when inserting the 3G modem:

Mobile connection not possible.

-Set your current mobile device as the default device in the ‘Manage Devices’ view

-Ensure that no other programs are using your mobile device and try again in a short while

-Delete the device in the ‘Manage Devices@ view, add it back again, and then try connecting.

If this error persists, please contact Support at your mobile network operator.

Support information RAS error code 680

Here is how I managed to (finally) get the USB stick to work (instructions for Windows Vista):

1. Go to ‘Control Panel’
2. Double-click ‘Device Manager’
3. Expand ‘Network adapters’
4. Alternate-click ‘Vodafone Mobile Broadband Network Adapter (Huawei)’.
5. Click ‘Uninstall’ then ‘Ok’.
6. Remove the USB 3G stick and reinsert.

There are apparently multiple things that may cause these USB sticks not to work but the procedure as above got mine working.
