Welcome to Vodafone Community
Its a familiar story I'm afraid. People move house and they find that the Vodafone coverage in their new area is no where near as good as in their old area.
While this is not good for you it isn't Vodafone's fault as you could have checked the coverage maps for yourself to see how the signal was likely to be in your new area.
All networks have areas where the signal is weak and that is something we all have to out up with.
Vodafone are providing a network and it is your circumstances that have changed not theirs. You are unlikely to get any discount on your contract but one of the forum team will be along soon to discuss your situation with you.
Thanks for your post. I can certainly sympathise with your circumstances if you did receive good coverage at your old address but the coverage isn't sufficient for data usage at your new address.
It appears that when you've contacted our customer care team that they have run through all of the options available in terms of trying to make sure that your phone is provisioned correctly for data usage. I appreciate that being advised to go out of the area to use data may seem a little far fetched, however the network is still available for voice, text and data and will be a little slower as it's on 2G rather than 3G.
You can check your network coverage here - Vodafone Coverage Checker - along with future upgrades in the area. Unfortunately we cannot be held responsible for a change in your personal circumstances so we're unable to offer an early termination of your contract without the early termination fee.
