When my Vodafone iPhone a week ago iTunes told me there was a update carrier settings, but I decided not to install it and enter the data by hand.
Later i downloaded that ipcc to the computer to see what apn I was getting, pure curiosity. Which was very surprise when I found what you see above, Vodafone sets different settings for the internet connection and for tethering, so it is very easy to detect it for them; that ready.
Well, the solution it's very easy (beware, maybe vodafone has other ways of detecting it). Do not install these operator settings and enter them by hand. If you already have them, you will have to restore so that the same options as me appear in the settings.
And in mobile data network you must put:
