Notice periods and dates
Provided without warranty, your contract is decisive:
- Notice period
- usually 60 days before the desired contract end
- Minimum term
- often 12 months, up to 24 with a discounted device
- Late or early cancellation
- remaining monthly charges keep being billed
- Details in the letter
- name, customer number, service/number, date
- What counts
- receipt at Swisscom, not the date on the letter
- Recommended sending
- registered mail or A-Post Plus as proof
Cancelling a Swisscom contract: count the notice backwards
The 60 days are where most cancellations fail. Count 60 days back from the last contract day you want: by that date the cancellation has to have arrived at Swisscom, not to have been posted. Anyone cancelling inside the minimum term or too late keeps paying the remaining monthly charges, according to Swisscom. With a subscription that includes a discounted smartphone the minimum term often runs 24 months, while the mobile part alone would already be cancellable.
On its own help page Swisscom names the hotline, the callback service and My Swisscom as cancellation channels. A letter is still worth sending: it proves what you cancelled and when. State your name, the customer number, the services affected (mobile, internet, TV) with the phone number or connection address, and the cancellation date you want. Depending on the service the contracting party is Swisscom (Switzerland) Ltd; the postal address in the imprint is in the name of Swisscom AG. Your customer number is what makes the letter identifiable.
What is special about Swisscom
- Swisscom names the hotline, callback and My Swisscom as cancellation channels. The letter is the channel that documents the date.
- When switching provider with number porting, better not to cancel yourself: porting through the new provider ends the contract, otherwise you lose the number.
- Bundles (internet, TV, mobile) and device instalments can run on different terms. Write precisely which services are to be cancelled.
- The postal address in the imprint is in the name of Swisscom AG. Depending on the service the contracting party is Swisscom (Switzerland) Ltd, which is why the customer number belongs in the letter.
Recommended shipping method
For a cancellation, receipt by the provider usually counts. With registered mail (from CHF 8.99) you have proof that and when your letter arrived. A-Post Plus with tracking is the cheaper option, simple sending is possible from CHF 2.49. This is a recommendation, not a guarantee.
