When did you send in the deregistration document? Did you also send in proof of your permanent residence abroad? Did you complete the form? https://www.o2online.de/assets/blobs/pdfs/contract-cancellation-moving-abroad/

Thanks for your quick answer!  I sent the document about 3 weeks ago.  I did not complete that form, but sent a letter from USA where I live with my permanent address noted in the letter.  Why should I have to agree to the 3 month basic fee?  As I understand by German law, one has the right to cancel all contracts when there is a permanent departure from Germany.   

Can you check the number to see if the notification has been received?  Should I send them here in this chat?   I tried calling but was on hold for 30 minutes and I gave up hope.  Thank you! 

No, your understanding is incorrect. Broadband contracts can be cancelled by paying 3 months basic fee, for mobile contracts there is no statutory  right of early termination at all, but providers generally apply the same rule as a gesture of good will.

You are communicating with other customers here in the forum (this is not the chat). You will need to send the documents to the address or fax number shown on the form.

Hi @Jov, 

welcome to our English Community. 

Nice that @bs0 already gave you some helpful suggestions. Thanks a lot for that. 

In order to terminate your mobile phone contracts because of moving abroad, we certainly need your agreement on paying a 3-month-fee. 

Did you receive any letter that we still need certain documents from you?

Loving greetings,
