O2: How to cancel your cell phone contract

At O2, you can cancel your mobile phone contract either online or by post. We show you both options here and have a ready-to-use letter of termination for you to download.

Termination at O2: By mail and by post

• At O2 you will find all information about a contract termination in your account "My o2". You can also find out more about deadlines and conditions for termination in the extensive FAQs. As is so often the case with 24-month contracts, there is a three-month notice period.
• Only the tariffs "o2 Genion S without cell phone", "o2 o" and "o2 Blue Flex" are an exception: 6 weeks for "o2 Genion S without cell phone" or 30 days for the other two tariffs. Find out in good time about contract terms and other offers so that the cancellation runs smoothly.
• The easiest way to cancel at O2 is to use our O2 cancellation template. Send the letter to Telefónica o2 Germany GmbH & Co.OHG, Kundenbetreuung, 90345 Nürnberg.
• Alternatively, you can also cancel online: To do this, go to "My O2" and go to the item "Note cancellation". Now you have to call O2 again and confirm that you really want to quit.

• You can also use the pre-formulated letter from our partner Aboalarm (see below) and their cancellation service if you do not want to take care of sending the letter yourself.
• The service costs EUR 3.49 or EUR 4.49 depending on the payment method selected. Proof of termination is of course included in the price.
