Issues with Dial up connection using Vodafone USB modem, Windows 10

Hi Jay,



Thank you for writing to Microsoft Community Forums.



We understand how difficult it could be. However, we would need some more information regarding the issue.

1. Do you see network signals showing as connected in the taskbar?
   
2. May I know the model of the Vodafone modem you are using?
   

Please refer to
Mobile Broadband Software for Windows 10 for the list of modem models which support Windows 10. We would suggest you to download the software utility from the article and check if it resolves the issue.



We would also suggest you to follow the steps mentioned below to check for the drivers for modem.

1. Connect the USB modem.
   
2. Open Device Manager by searching for it in search bar.
   
3. Locate and expand Universal serial bus Controllers in the list.
   
4. Check if the driver are displayed under the tree.
