Dear @emeltoprak ,

welcome to our community.

Are you using the latest app version?

If you can only use an older version of the app due to your handset, please do not log in with the email address, but register again with the phone number if necessary.

You can also try deleting the cache and app data in the settings of your smartphone on Android and reinstalling the app if necessary or, on iOS, closing the app once in the task menu and then reinstalling it. In this way, faulty data will be deleted.

Kind regards,

Andrea

Hi, 

I am encountering the same problem since then and up until now it says the same. I have tried deleting and re-installing the app the errors is the same. Nobody from the customer service hotline can help me and give a solution.

I hope someone can help me here.

Hello @AnneJelly,

Please log in to the app with your phone number instead of an email address. If you haven't registered yet, you can do so here: Mein o2 - Registrierung

Please always use the latest version of the My o2 app.

Please let us know if this has solved your problem.

Best regards

Giulia
