All you need to do is to plug-in the USB modem into a USB port of your computer and wait for the application to start. Beside the actual software it will also install drivers. If it's not working then you will need to install the drivers manually using Device manager (you can find it when you click My Computer > Properties) and then browsing to the Drive of the USB stick in My Computer. These instructions are available for all the USB modems, but if you encounter problems you should contact the Vodafone service.
