You can try to check your account type on your vodafone software as the following steps:


- Vodafone Mobile Broadband software: Click on the advanced Tab => Click on the white antenna at the top left corner => go to options => account type => make sure it is matching your Plan.


- Vodafone Mobile Connect software: go to settings at the top => change account type ==> check that its matching the plan.



Hope this might help

Thanks for your answer. but it does not work..


Actually, I'm prepaid account. But I keep getting that error while trying to connect network. After I change account type to 'contract'. I can connect to the 3G network, but I could not get the ip address.... that's weird...

Have you disabled the wifi and removed any ethernet or other broadband connection before trying to connect with 3G?.  Reboot after disabling.


Some VMCs will try to connect to "best connection" and if that's wifi the 3G will not connect.

:smileywink: Change account type makes it work.

Make sure to try to uninstall the Vodafone network adapter if still doesn't work.
