Since my old contract was too expensive and I have not really exploited with all the Drumrum Allnetflat, I decided for a map of DeutschlandSIM. Since I had never carried out a number portability, I had a bit worried that it all works. Announced online and form for the bidder Altan printed ... Completely unnecessary, as it turned out later. When you activate the card, the number portability choose comfortable and a short time later everything was successfully launched on the stage. The activation of the new card went smoothly. On the eve of the change inserted in the morning "no network" stated newly launched mobile phone, ran. What more do you want?
Whether the limits range, of course, everyone has to decide for themselves. But I think that for each of the appropriate tariff is likely to be there. I particularly like the 1-month notice period. I just get tired of the usual 2-year-restrictive contracts.
Conclusion: So far I could not find anything negative!
