Hello @Zain001,

welcome to our o2 Community

The easiest way to cancel your contract is our online cancellation form: Ihr Kündigungswunsch | o2 (o2online.de)

Here you can also cancel your contract early (Außerordentliche Kündigung) because of moving abroad.

You will have to upload a copy of you deregistration form there (from the Einwohnermeldeamt).

Bumer’s link is also correct, but a little outdated with the paper form.

Please let us know if you have any further questions.

Best regards

Giulia

Thank you, @Bumer  and @o2_Giulia , for your assistance.

@o2_GiuliaThe link you provided is helpful. However, I’d like to clarify: when I cancel the mobile phone I purchased using that link, will O2 automatically deduct the remaining balance? I’m ready to make the phone.

Also, I didn’t see an option to upload my deregistration documents through the link.

Hello @Zain001 

yes, if you still have an active bank account with direct debit authorization for the deduction.

You can send the documents to the address stated in the article which Bumer shared.

Best regards,

Michi

Thank you @o2_Michi The detailed informations are helpful.

Hello @Zain001,

could you already sent the documents to our address?

Best Regards,

Gerrit

Hello O2 Team,

@o2_Gerrit Thank you for your supportive response to my message.

I have sent my deregistration document along with an additional letter to the office address provided in the link shared by @Bumer . I have also completed the online cancellation process using the link provided by @o2_Giulia . I hope this will facilitate the successful completion of the payment and cancellation.

Thank you.

Best regards.
