Are you using Windows 10 ? If so please read the important information in this link.
Windows 7 Link > Mobile Broadband Software for Windows 7
A few further questions if I may.
Has the device worked before ?
Is this a new dongle ?
Is the Sim Card Activated?
Do you have enough Data to connect ?
Is your Network Signal Ok. Check here > Official Vodafone Network Checker.
Are drivers up to date on your computer or required ones downloaded ?
Have you tried the device in another computer?
Are any firewalls or security suites tweaked to allow the devices access ?
