Revoke and cancel a contract - you have to be aware of that

If you have changed your mind after concluding the O2 contract, you can use your right of withdrawal and cancel the contract. We'll explain how to do it.

Cancel O2 contract: submit revocation

In order to cancel an online, telephone or postal contract with O2 - for no reason - you can use your right of withdrawal. This applies up to 14 days after conclusion of the contract.

• With O2 you have to cancel a contract in writing. This can be done by post, fax or email.
• The revocation must contain your full name, your address, the contract number and the contract name and the date of the conclusion of the contract.
• You can formulate the revocation yourself or use the template from our partner Aboalarm.
• Send your written revocation by post to Telefónica Germany GmbH & Co. OHG, Kundenbetreuung, 90345 Nürnberg, by fax to 0800 22 111 23 or by email to
• Please note that a mobile phone contract that you have concluded in a local o2 shop is not subject to the right of withdrawal mentioned above. Withdrawal from a contract is therefore only possible in exceptional cases and depends on a goodwill opinion from the respective shop.
