Bit absolutely satisfied.

Ordered SIM card, hit the next day (one is Amazon otherwise usual) with me.
Unfortunately, the online activation did not work out this time. So called directly at DeutschlandSIM and luckily I had not great shimmy by any audible menus, special call was taken promptly by a nice lady contrary.

Since my old contract expired in late March, I wanted to take my number. Everything went absolutely smoothly across the stage. I am thrilled with the hassle-free communication. I was always kept informed about the status via e-mail. Just in time for the announced date I could activate the card and use directly.

Other phone providers may learn a lot here.
