I live in Switzerland and we have quite a lot of unlimited plans without speed limit after a certain amount of data. Also the price in relation to income is not that high. If I compare it to Germany, where you can get no real unlimited plan and very often have a bad signal even in cities, and also in relationship to the income there, Germany seems to earn a place much lower on the list.
So this comparison seems a bit odd, and should be divided into prepaid plans with limited data packages and unlimited plans.
