It doesn't help that German politicians think it's a good idea to let companies bid on frequencies - 5g frequencies just went for 5.5 billion to 4 large companies. So those now have the monopoly on that plus they have to earn it back from the customer. And the highest bidder got the best frequencies. So good coverage can only be achieved by one company. Same happened with 4g & 3g beforehand. Result being, only profitable areas are covered and competition has no chance to get into the market. Sadly in German politics it's easier to get voted for tax cuts (because they get money by selling frequencies) then promising good internet coverage :(
