I am infrequent users and use your smartphone for a few mails. The promotional price of 2.95 EUR for 50 minutes, 50 SMS and 100 MB is exactly what I was looking for. I was previously at O2 and have changed only because of the collective. With DeutschlandSIM, activation I am so far fully satisfied. I chose a desired number 7.50, because I think that with more than 20 too high turns the number portability.
