Hello,
I wish to take a O2 contract from a friend. I would like to know the procedure so that all the future billings will be on my name and from my Bank account.
The contract is for a Mobile connection, for 2 years and it is the 4th month.
Best,
Jibi
Dear
welcome here in our community. 
In order to take over a contract, a so-called change of contract owner must be initiated. The previous contract owner can request this under My o2 and the new contract owner will then receive an email confirming the change. If you understand German or have someone to help you with the translation, I have an article here where everything is explained: Vertragsinhaberwechsel bei o2
Kind regards,
Andrea
