    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.
    
    So, you are the best choice, and if i got something else to unlock, i will come to you again.
    
    Thank you very much.

I just got the Unlock code from Telekom. A wonderful surprise. I did not think they would have done so.
Thanks for the assistance. Let me know if you could use the pin to revers engineer the solution or proof your program. 🙂
