Ruhr area is not very far from here. I will be on the lookout for self-registers next time I'm in Essen!

As for mobile networks, I think all of them are frequently unusable in rural areas. Between Aachen and Cologne (I most frequently travel there), which is not a quiet route, I think at least half the time there is 2G or nothing at all. I should measure that some time. My work phone (Telekom) doesn't have better reception than mine (Dutch network using O2). Without measuring, I would actually estimate that O2 is the better deal around here.
