If you want to cancel a Sunrise Mobile, Internet or TV subscription, you should carefully check the contract, minimum term and current price information. The background is a consumer-protection lawsuit against Sunrise that became public in September 2024. It concerns clauses in the General Terms and Conditions (GTC) relating to price adjustments and customers’ cancellation rights.

Important context: the sources mentioned in the briefing document the filing of the lawsuit and the Sunrise information applicable at the time, but not a final, legally binding Zurich judgment. Anyone searching for a “Sunrise cancellation clauses judgment” should therefore distinguish between the pending or reported proceedings, a first-instance decision and a final decision that has entered into force. The agreed terms continue to apply to your specific contract unless a court has set them aside or amended them in a binding manner.

What are the proceedings against Sunrise about?

According to a report by Netzwoche, consumer protection filed a lawsuit against Sunrise with the Zurich Commercial Court. The challenged GTC clauses give Sunrise scope to make price changes and may at the same time restrict customers’ ability to withdraw from the contract when prices increase.

The legal principle is simple: a subscription is a contract. It contains the price, services, term and cancellation rules. If a provider increases the price during the contract term or changes essential services, the question is whether you must continue the contract under the previous terms or may cancel it extraordinarily.

On its page about new prices, Sunrise explains that price changes are communicated and that a cancellation right may exist under certain conditions. However, the notice concerning your specific subscription, the date of the change and the version of the GTC applicable to your contract are always decisive. So do not read only the general information; also check the letter or email about the announced adjustment.

Ordinary cancellation: the minimum term and notice period remain central

An ordinary cancellation is the regular termination of your subscription on the next possible contractual date. Two points must be distinguished:

  • Minimum term: during an agreed minimum contract term, you can submit a cancellation, but it will normally only take effect at the end of that term. Early termination may incur costs.
  • Notice period: after the minimum term has expired, you must comply with the contractual notice period. What matters is when Sunrise receives the cancellation, not when you send it.

Check your order confirmation, customer account and the GTC you accepted at the time for the start of the term, any discounts tied to a commitment and the notice period. Particularly with discounted bundled offers, the commitment may differ for individual services. Therefore, check Mobile, Internet and TV not only as a package, but also separately.

If you are planning a switch, the overviews of Mobile subscriptions, Internet subscriptions and TV offers will help you compare services and contract models objectively.

Extraordinary cancellation for price adjustments: not automatic, but check carefully

An extraordinary cancellation is a cancellation that may be possible before the minimum term expires or outside the normal notice period. In the event of price adjustments, it does not depend solely on whether your bill is higher.

In particular, check:

  1. What has increased? Is it the monthly base price, an option that was previously free, fees or a service that is now becoming chargeable?
  2. When was the change communicated? Record the date of the email, letter or customer-account notification.
  3. What cancellation option does Sunrise specify? A notice may provide for a specific deadline and cancellation method.
  4. Is your subscription actually affected? Price lists or adjustments do not necessarily apply to every older offer.
  5. Which GTC applied when the contract was concluded? The version referred to in the contract is an important point of reference. Later changes must have been communicated to you.

If you want to switch, you should not silently accept an announced price increase. Refer in writing to the specific notice and ask for confirmation as to whether Sunrise accepts early, cost-free termination of the contract. If you do not receive a clear answer, keep all correspondence.

The proceedings in Zurich may affect the legal assessment of such clauses. However, they do not replace an individual review: whether you can cancel extraordinarily in your case depends on the contract, the specific change and the applicable law.

Number porting: taking your number with you does not end every obligation

Porting a mobile number is organisationally different from cancelling a contract. When switching to a new provider, you request that provider to take over your number. The new provider coordinates the technical switch with Sunrise.

This is convenient, but it does not automatically mean that an ongoing minimum contract term ends without consequences. If a commitment exists or Sunrise charges costs for early cancellation, these may still apply despite the successful number transfer. Additional options, device financing or other services in the same customer account may also continue.

Before requesting porting, clarify in writing:

  • whether your Sunrise Mobile subscription ends on the porting date;
  • whether a minimum term or notice period prevents this;
  • whether costs for early termination apply;
  • whether options, additional eSIM contracts or other numbers must be cancelled separately.

For Internet and TV subscriptions, there is no number porting in the same sense. You must arrange the cancellation directly with Sunrise and coordinate the activation with the new provider accordingly. You can also find information about switching providers in our guide.

Checklist for Sunrise customers

If you are affected by a price change or want to cancel your subscription anyway, proceed in a structured manner:

  • Download the contract, order confirmation, current bill and relevant GTC version.
  • Note the contract start date, minimum term, notice period and earliest possible cancellation date.
  • Save the notice about the price or service change, including its date and complete content.
  • Cancel in writing via a traceable channel and state your customer number, the affected services and the desired end date.
  • In the event of a price adjustment: explicitly request confirmation as to whether Sunrise accepts a cost-free extraordinary cancellation.
  • Request written confirmation of the cancellation with the end date.
  • For Mobile porting: start the request with the new provider only after clarifying deadlines and possible costs.
  • Keep emails, PDFs, screenshots and proof of dispatch.

In a dispute about the interpretation of the contract, documented communication is crucial. A cancellation without confirmation, a purely oral statement or an unrecorded notice in the customer account are much more difficult to prove in the event of a conflict.

What this means for subscription customers in Switzerland

The Zurich proceedings show above all that price changes, cancellation and switching providers are not the same thing legally. A minimum term does not necessarily protect the provider against every early cancellation, but a price increase also does not automatically create a right to extraordinary cancellation in every case.

You should therefore check your individual contract, respond to price notices within the stated deadline and not rely solely on porting when switching. Until there is a decision that is binding for your case, clear written documentation is the best protection against unexpected charges.
