Welcome to Vodafone Community
When trying to login to myvodafone account I am taken to a maintenance page, this has been going on for many months now. I have cleared cache etc but this has not solved the problem. Also tried different browers and have the same problem
The site is working as it should be. You need to clear everything on your PC, including all cookies. Close down the browser, give it a few minutes to settle down and try again.
Google Chrome seem to work well with Vodafone.
