Notice periods at Swisscom AG

Notice periods explained

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 Swisscom AG, 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.
