I had an iPad 4 made me for Christmas and of course wanted to also surf the Internet. The SIM card was very fast there, and I have the same inserted to test. The iPad showed me that no power is there, and then I read about in guidance and Internet, as the thing can be activated. On my internal side at T-Mobile I got the message that the card at this point can not be activated. Then inquiry has given me the Telekom on tel explained that I have to go to the dealer, who is obliged to activate -. At 600 km distance from here to Hamburg, too easily ....... Then I contacted the dealer, who promised me for the next day the activation; Ultimately, however, I still could not use the card after 1 week because it was not activated. Then I have helped someone in the telecom and me the right hotline number. given that my card number. has so requested, and the next day my card worked. I mean that Telekom here over the Internet and dealer sells a product that is not available without further ado.
