I have now ordered broadband and obtained my connection userid and password.
When I requested these details, I was asked what router I was going to use as I was told they use different connect details for different routers. Seemed strange to me, but it was easy to tell the truth as I now have a Zyxel VMG8924-B10A.
I have had Vodafone mobile phones for some time and at the moment the price is £25pm. No mention of the price increase so far!
