Cancelling a Salt subscription: the written route

Salt is one of the few Swiss telecom providers that names the postal route itself: for a written cancellation the help page points to registered post to the Prilly address. As an alternative Salt gives the hotline 0800 780 100. Anyone who wants to be able to prove the cancellation date is better served by registered mail, because it documents receipt and date.

Count the 60 days back from the end of the minimum term, not from the end of the month. The letter needs your name, the customer or contract number, the phone number concerned and the cancellation date you want. If you switch provider and want to keep the number, porting runs through the new provider; in that case do not also cancel yourself.

What is special about Salt

  • Salt names registered mail itself as the route for a written cancellation, which makes the proof undisputed.
  • Older Salt documents show the previous address Rue du Caudray 4, 1020 Renens. The current help page gives Avenue de Malley 2, 1008 Prilly.
  • The notice period relates to the end of the minimum term. Check in your My Salt account when that expires.
  • Prepaid offers and subscriptions with device instalments follow their own rules. State in the letter exactly which contract you are cancelling.

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.
