Mobile-wise things are much improved over a few years ago. All networks seem to get reasonable cover, though there are still a few blackspots, especially indoors. Used to be that Vodaphone was the only network with much of a service, but that is no longer the case.

If you were in Staithes, however [just a few mile up the coast] I am given to understand that the only network worth a damn is Orange, and even they have big gaps.
