    Thank you very much.

  2. Hello, i need also a code.


    The 10 dollars for your support will be worth, i think so.

      • Hello Kumar,
        After i had little trouble, you helped me very quick (within a few seconds) and now the router is unlocked.

        It was a good decision to pay the 10 dollars for you, because an unlocked router will cost 80 dollars at amazon.
        The router i got from the deutsche telekom because of internet problems in february. But it was locked. If i want to unlock this at telekom, so
        1. i must wait 2 years (then it is automatically unlocked, or for free or
        2. i must pay 100 Euros for them.

        Thank you very much.
