I can DeutschlandSIM nothing negative. Am now become the 5th year here and it has always worked out everything. Well, the activations sometimes take a bit too long, but I had never get rejections. Must say that currently run 4 contracts in my name! The Hotline could always help. Advantage: The Hotline has a normal landline number and not 0180 or the like. When choosing DeutschlandSIM was the price in the first place. I do not see the other providers who still think that they have. To throw a monopoly such. Ex large T, money down the throat if I get the same or better performance cheaper elsewhere. Anyone who thinks that having to go to the Giants, who will do that. Then money seems to play no role. Anyway, I'm staying with and DeutschlandSIM. From my clear recommendation to the full 5 stars!
