Hi, apologises for not speaking German, yet!  

I am moving to Bonn later this month and would like to sign up for internet and a mobile contract to start when I arrive on 18th August. I can’t place an order online without a German phone number as the system won’t let me. I also can’t contact the English speaking hotline as I am currently in Switzerland. Is it possible to take the contracts out before I arrive? I have a German bank account and my apartment in Bonn used to be connect to Telekom. Thanks
