Wish for termination

you can use this form, a street and house number are not necessary,

this is correctly addressed via the postcode.

please try Fax +49 1805 57 17 66

You do not need a street or house number. The address is correct as it is. Yes, if you send a FAX from another country you would of course need to add the country code 49 for Germany.

I have used two services for fax sending, but i have received only this:

We could not send fax to number +491805571766. 

That happens all time. What do I do wrong? 

the phone number is chargeable,

therefore the sending will probably be refused.

So for me there is no option to send a fax with termination?

If the number is not reachable from the country you are in / service you are using then no.

Does anybody know the street and the house number to send the termination via post. In my country that is necessary to mention street and house number.

Hi @Alex2323, 

please use only this address in order to send a cancellation: 

Telefónica Germany GmbH & Co. OHG

Kundenbetreuung

90345 Nürnberg

Just have a look also here: cancellation possibilities

I have never heard that a cancellation did not arrive at o2 because we do not have a street and housenumber. 

Loving greetings,

Tobias
