Where to see how much mobile data i have in "Mein o2"?

Hello ​@Dqvld,

welcome to our o2 Community 😀

Please excuse the late reply due to the holidays.

You can usually see the remaining data volume directly on the start page of the app. Alternatively, you can check your consumption also in the customer portal Mein o2.

Please let us know if have further questions, we are happy to help you.

Best regards

Giulia
