Hello @TPORPACZY,

if you are able to log in to our o2 online portal and can already access the Mein o2 area you should already be able to see the monthly billsm don’t you?

What happens if you try to open an invoice? Do you recieve an error message? Ifyes, what does it say? Have you also tried to use the Mein o2 App on your mobile phone and view the invoices there?

Regards,

Lars
