Welcome to Vodafone Community
I have just moved house to a new county (from Surrey to Wiltshire) and I have changed my postcode in the sure signal dashboard.
However, when I connect my sure signal and it has registered itself on the network (after about 2 hours) I get "no signal" on my iPhone 4s (it was working OK before).
I have disconnected the sure signal (I get some signal at my new address) but now I am getting texts from vodafone saying that I need to change the postcode.
I checked last night that the postcode that is registered is correct (it is) so I tried connecting the sure signal again but got "no signal" on my phone again.
