Four steps, about three minutes. No account, no printer, no trip to the post office.
Start from this page — we already hold Sunrise GmbH's verified address and the correct notice periods, so there's nothing to look up.
Add your name, address and customer or contract number, pick the termination date, and sign online with your finger or mouse.
kündigen24.ch prints your cancellation and posts it to Sunrise GmbH as registered mail — the format Swiss courts recognise as proof.
You get the tracking number and a copy of the signed letter, and can follow it until Sunrise GmbH has received it.
Have these on hand and you'll be done in one sitting:
| Contract type | Notice period | Cancellable |
|---|---|---|
| Mobile subscription | 60 days | End of minimum term, Monthly thereafter |
| Internet & TV | 60 days | End of minimum term |
A notice period is how much warning your provider legally requires before a contract can end. Miss it and the contract usually renews for another term, so timing matters as much as wording.
At Sunrise GmbH, the shortest notice period we list is 60 days. Send your letter so it arrives before that window closes.
You can cancel for a specific date or simply for the earliest possible date. The latter is safest when you're unsure, because it can't be rejected for bad timing.
We send every letter as registered mail. That gives you a dated, tracked proof of delivery — the evidence you'd need if a provider later claims it never arrived.

This is where your letter goes.
Sunrise contracts renew automatically unless cancelled in time. Once the minimum term has passed, most subscriptions can be terminated monthly with 60 days notice.
Yes — it is on every Sunrise invoice, top right.
