Earlier quoted context omitted.
I have had the same experience both in Germany and in some areas of the UK, like downtown Cambridge which was shocking. In contrast, both Scandinavia and many parts of Southern Europe have great mobile and landline Internet. I guess it has something to do with the structure of the market before EU enforced massive privatizations.
It is partly down to inept politicians and the concessions they dictated to the mobile networks. In Norway, they demanded the networks cover 97% of the geographic areas. It's why you might get 3G or even 4G in the middle of nowhere, on top of a mountain, wherever you might drive. However, in the UK the inept politicians demanded 97% of the population, not geographically. So all the UK networks just built perfect cove…
Which is completely backwards. You don't need mobile where you live (as long as you can get a landline), you need it everywhere else.
