So what AMAZON offers here an absolute impudence !!! I had ordered this directly through Amazon a white BlackBerry Z10. When I had since unpacked and turned on sGerät appeared a telecom start-up screen. Even when a shutdown Telekom screen could be seen. Verscherbelt AMAZON now about even the rest of the goods Telekom or what should the crap. That's a real customer deception. If I buy a contract-free device on the market, I expect a free device without software or hardware branding.
Addendum: Okay, so it looks like the problem is not with Amazon, but the BlackBerry device. It indicates the operator whose SIM card is able to read it. At Telekom, the operating system of the BlackBerry is changed so much that at a change of operator only to reinstall will help. That's really scary!
