Hi,

 

I would like to access the My o2 app in order to view my bills, however, I am unable to login. Everytime, the app shows the error “Da hat etwas nicht geklappt”. How do I circumvent this?

    Are you already registered with your phone number for my o2? Are you logging into the app with your phone number as your username? Does logging in to the customer portal work?

      Hello ​@RudiB69420,

      welcome to our o2 Community 🙂

      Could you access your contract in the My o2 app or via a webbrowser with Bumers advice?

      Best Regards,

      Gerrit

      Hi, when I try to use my phone number to login, it does not work. When I try to login to the my o2 website using my email, it just redirects me to the community website.

      What exactly doesn't work when you log in with your phone number as your username?

        Good morning ​@RudiB69420 😊
        It sounds like your phone number hasn't been registered yet. Bumer has already asked the question here: What exactly doesn't work when you log in with your phone number as your username?
