The problem is that websites use databases that convert your I.P. address to a location, unfortunately those databases are notoriously inaccurate for Vodafone I.P.'s.
Also Vodafone brought many addresses over from their Indian operation and sometimes the databases still have the original location.
I don't believe there is much use users can do about it.
My favourite location website is infosniper.net, which currently puts me in Leeds when I am actually in S.E Essex.
