You have to register your o2 DSL contract with the landline phone number (German: Rufnummer) that belongs to your o2 DSL contract before you can use “Mein o2”. After that you can long-in to “Mein o2” with your phone number and click on “Rechnung”. If no invoice has been created yet, you can of course not look at an invoice. You will be notified by e-mail about the availability of an new invoice in "My o2".
