When users want to cancel a mobile plan, there can be many reasons:

- moving to a new place,
- poor network coverage at home,
- changes in personal needs regarding calls and data usage.
In most cases, cancelling a mobile plan is straightforward as long as you pay attention to the minimum contract term and the notice period. However, if you cancel early, you usually have to pay the remaining monthly fees until the end of the contract.
If you are wondering, “How do I cancel my mobile plan?”, you are in the right place. This article provides all the key answers.
Cancellation options: How can you cancel a mobile plan?
Swiss mobile providers offer different ways to cancel a plan. Depending on the provider, cancellation may be possible:
- by phone,
- by post,
- by email,
- online, or
- via chat with customer service.
Please note: Not every provider accepts every channel, and processing times can vary.
Cancellation by phone
Many providers such as Swisscom, Sunrise or Salt allow cancellation via their customer service hotline or even offer a dedicated cancellation hotline. Cancelling by phone is fast, but often requires additional written confirmation.
Cancel a contract online
Some providers offer an online cancellation form, available either in the customer portal or on their website. This option is especially common with Yallo, Wingo or Migros Mobile. Processing by the provider’s cancellation department usually takes a few days.
Cancellation by post (address)
Cancellation by post is almost always possible and used to be the standard method. Written cancellations are recommended because they provide clear proof. You can find the provider’s address in your contract or on their website.
Cancel a plan by email
Cancelling a mobile contract by email is possible with many providers, but it is not always sufficient. If accepted, you will usually receive a confirmation. Make sure to include all contract details and to comply with the minimum contract term and notice period. Often, providers require the use of a specific cancellation form.

Cancelling a mobile plan by provider – a quick overview
Each provider has its own contract terms. Below you will find concise guidance on how to cancel your mobile plan with individual providers and what to watch out for.
Cancel a Salt plan
Salt offers two basic types of mobile contracts:
- Contracts with a 24-month minimum term (Mobile & Home) are renewed monthly if they are not cancelled with 60 days’ notice before the end of the month.
- Contracts without a minimum term can be cancelled at any time with 30 days’ notice before the end of the month.
A Salt plan can be cancelled by phone, by post or online. If you cancel before the end of the minimum term, you must pay the remaining costs.

Notice periods of providers – overview
The notice period depends on your contract and varies among Swiss providers between “anytime to the end of the month” and a notice period of up to three months. If you cancel too late, the contract is automatically extended and additional costs apply.
Depending on the provider and product – mobile, internet, TV or fixed line – there may be differences. Some mobile plans have a 24-month minimum term, while others are flexible with no minimum term. The overview below compares individual providers and shows why it is important to know both the notice period and the end of the minimum contract term.

Cancelling a plan early: costs & special cases related to the minimum term
Early cancellation means ending the contract before the minimum term expires. In this case, additional costs usually apply, as the remaining monthly fees are charged until the end of the contract. Early cancellation is rarely free.
However, there are some exceptions:
- price increases,
- if the provider cannot offer service after you move.
In such cases, cancellation before the end of the minimum term may be possible without a fee. Always check your individual contract terms. If you are unsure, send an SMS with the text INFO to 503 to receive details about your contract duration and early cancellation costs.

Early cancellation of a Salt plan
With Salt, cancelling before the end of the minimum term usually means paying the fees for the remaining months. In the case of price increases, you can usually cancel immediately.
Cancel a Swisscom plan before contract end
With Swisscom, early cancellation also results in remaining costs according to the contract. Special rights may apply in case of contract changes.
Early cancellation of a Sunrise plan
Sunrise also charges remaining monthly fees for early cancellation. In certain cases, special termination rights apply, allowing early cancellation of the existing contract.
Keep your number or cancel it? (Number portability explained)
When switching plans, the key question is: keep your current number and transfer it to the new provider, or give it up?
Number transfer is done via portability.
Important: After cancelling the old contract, the new provider usually handles the number porting process. Timing is crucial to ensure your current number remains active and reachable.
Cancel a mobile plan with number portability
If you want to keep your phone number, the new provider requests the porting. Your number is transferred from the old provider to your new plan.
Cancel a plan without keeping the number
Without porting, your number is deactivated after the contract ends. The number is lost and may later be reassigned to another customer. To avoid this, make sure to inform both the new and current provider in time if you want to port your number.

Common cancellation problems – and how to avoid them
With good preparation and the right information, any contract can be cancelled properly. Here is how to avoid or solve the most common issues:
- No or delayed confirmation: Follow up and request written confirmation.
- Ongoing billing despite cancellation: Check the cancellation date and contact customer service.
- Porting issues: Align deadlines and inform the old provider.
- Unintended contract extensions: Do not agree to changes by phone without confirmation.
- Cancellation rejected after deadline: Make sure to respect the notice period and cancel in time next time.
Not cancelling, but switching instead? Consider alternatives
Instead of cancelling without a new plan, it can be worthwhile to compare mobile plans from the same provider. New plans often offer more data, better roaming options or lower costs for the same services.
If there is no suitable option with your current provider, switching to another provider is usually straightforward. The alao mobile plan comparison helps you explore offers from the best Swiss providers and sign up for a new plan in just three clicks.
If your life situation changes temporarily, it may also make sense to pause your plan. Contact your provider to find out what options are available.
