Hey @Four_oFour,

Have you already received the hardware invoice? There should be the number as shown?

Hi,

I only have the Auftragsnummer, and ‘ihre referenz,  the contract number isnt there, from the invoice that I have atleast.Is there another way, I need to update my details.

Hello @Four_oFour ,

you’ll need the invoice that you get send some time after the order completes to register your myHandy contract. There you can find the “Vertragsnummer” that is required. Maybe this helps you with finding the correct number: https://www.o2online.de/meta/auth/subscription-id-help/
