The card came quickly and unlocking went more or less smoothly.
It must be said that the tariff is really cheap and frugal enough these claims out completely. Advantage you do not have months-long contract.
However, I have to say now that I once had problems with my internet and I never, and I mean never came through the Service Hotline. that's why I've tried to use the online help, but the answers were useless and unhelpful. As if someone had just typed a manual written off without any personal problem solving. And to be even more impudent will I ever got instead answers and help messages if I was satisfied with the service. Thrice filled negative still followed no help. The problem with the Internet is then solved a friend.
Now the second problem. I have ordered a replacement card for a new iPhone 5s and did activate the card. Now I wait for hours and nothing happens. Again, no chance by the Hotline to come back. Quick help is different. The second called Hotline starts with the fact that it is a stated are not enough there to meet people around the capacity of callers. Now I wait again for help from Sim Germany. ... Let's see how many customer satisfaction mail I get time.
I forgive only three stars because an online system is helpful, but if you you just need at a hotline and service expected.
