How can I terminate the telephone or Internet contract?
Most telecommunications providers also allow contracts to be concluded on the Internet; you can then also terminate your mobile phone or Internet contract online on the provider's website. Online providers have been required to set up an easily accessible cancellation button ("Kündigungsbutton" in German) for term contracts on their websites since July 1, 2022. With one click, you should be taken to the cancellation page via a corresponding button. You do not have to log in to do this. After terminating the contract, you will receive an electronic confirmation of receipt, which will serve as proof that the notice has been received.
You also have other cancellation options: With an e-mail, a text message, a fax (in "text form") or with a letter. In the cancellation you must declare that you want to terminate the contract. It is always important that the notice of termination reaches your provider in good time.
