Thanks John, all seems to back to normal. I would have thought as part of planned work it would have gone in network outages on the vodafone website. The call centre did say people had been ringing all day. It might have reduced their load a bit if it was linked from the network status page.
Does this mean I have to buy an LTE phone now? ;-)
My views (except when I am looking out their windows) are not those of my employer.
