How can I settle my O₂ phone installment contract early as I’m leaving Germany?

Hello,

I currently have both an O₂ phone connection contract and a phone installment contract for my iPhone. The phone contract still has around 14 months remaining (from December 2025 to February 2027).

Since I am leaving Germany soon, I would like to know how I can settle my phone contract early by paying the remaining amount all at once and close the contract completely.

Could someone please explain how to do this? Is it possible to pay the full remaining amount for my iPhone in advance and own the phone after that? Also, what is the procedure to cancel my O₂ mobile connection (SIM) contract because I am moving abroad?

Thank you in advance for your help!
