Hello

Apologies for not speaking German. My roommate moved out of the apartment, and left me Deutsche Telekom Speedport Smart DSL Modem/Router, all connected as it was. The contract was on his name, but it has now expired, and I am without internet. Can I sign new contract with Deutsche Telekom for DSL internet that would be on my name, but using the existing equipment (DSL model), just with new login details? Is there a waiting period after the new contract signig or I can use internet services right after signig (or next day maybe)?

Thank You!
