Cancel a German mobile contract with the right end date

To cancel a German mobile contract, enter when it started and when your notice will arrive: the tool shows the end date and writes the cancellation letter, including your number and porting wish.

How the check works and its sources

German mobile and broadband contracts with consumers may have an initial term of at most 24 months (section 56(1) TKG). After that they renew tacitly, but only for an indefinite period: you can cancel at any time on one month’s notice (section 56(3) TKG). For a contract from 1 March 2025 with 24 months, the minimum term ends on 28 February 2027; with one month’s notice in the contract, the cancellation must reach the provider by 28 January 2027. If it only arrives on 10 February 2027, the contract ends one month later, on 10 March 2027, not after another year. The provider’s terms may not require a stricter form than text form (section 309 no. 13 BGB): a letter, an email or the cancellation button on the website will do. The template’s letter, written in German, works for each of these routes.

Cancelling a German mobile contract: minimum term or one month

The minimum term ends the day before the calendar day on which it began, so a contract that started on the first ends on the last day of a month. The contractual notice period counts back from that day. Once it is missed, the old rule of another renewal no longer applies; instead one month from receipt does (section 56(3) TKG).

Special cases

If you move and the provider cannot deliver the service at the new address, you may cancel on one month’s notice. A one-sided change by the provider, such as a price rise, gives a special right to cancel. The letter does not mention either case; add one sentence stating the reason. If you also have a gym membership or an energy contract to end, those templates use their own rules.

Frequently asked questions

Tap a question to see the answer.

Can I cancel my German mobile contract monthly after 24 months?

Yes. Once the initial term has expired you can cancel a tacitly renewed contract at any time on one month’s notice (section 56(3) TKG). A cancellation received on 10 February 2027 ends the contract on 10 March 2027. The provider must remind you of this before the renewal.

Do I have to send the cancellation by registered mail?

No. The provider’s terms may not require a stricter form than text form or any special delivery channel (section 309 no. 13 BGB). An email to customer service or the cancellation button is enough. Keep the sent receipt or the confirmation, because in a dispute you must prove that it arrived.

What is the German cancellation button?

A business that lets consumers sign contracts on its website must also show a button labelled “Verträge hier kündigen” leading to a cancellation page (section 312k BGB). After you submit, the provider must confirm receipt electronically at once. The button is an extra route; a letter or email remains valid.
