On top of the fixed line telephony, Internet and TV & video services, this fee also includes a free Apple TV 4K box.
(Ref. "What is the cost of the Apple TV 4K?")

What are the setup costs for the Fiber Box and the Apple TV 4K?

The home setup of your equipment (Fiber Box and Apple TV 4K) costs CHF 199.95.
You can request this optional service separately during the order process.

What are the costs of the fibre plug installation?

In most cases, this service is included in the activation fee. However, in some special cases (condominium building, single-family home, division of a property, construction of an additional apartment, etc.) you may be charged for additional costs for the installation of the fibre optic plug.

  • If you wish to move an already existing fibre optic plug to a different room, the removal and reinstallation are not included in this service and will be at your cost.
  • The service includes exclusively the installation of the fibre plug (and not the device setup).

What is the cost of the Apple TV 4K?

The Apple TV Box 4K is offered to you, if you select it during the initial Salt Fiber ordering process.
In case of a subsequent order or if you choose to order additional TV boxes, you will be charged CHF 187.95/box.
Ref. Product & tariffs brochure

Do I need an electrician to install the fiber plug at my place?

If your building is connected to the fibre optic network but there is no fibre plug yet in your flat, a certified technician wil install one.
Therefore, it is important to provide us with a valid phone number and e-mail address during the ordering process, to ensure our service partner can take an appointment with you.

How long will it take to activate Salt Fiber ?

If there is already a fibre plug at your place, please provide us with your OTO ID when you order, to speed up the activation process.

In this case, the installation requires usually around 20 working days.

If not, an electrician first needs to install a fibre optic connection in your building and/or a fibre plug in your flat.

Hence, the installation and activation process can take up to 7 weeks.

OTO ID (de)
OTO ID (fr)

Is there a setup service for the Salt Fiber Box and the Apple TV 4K?

Yes, during the order process you can request a home configuration package for your equipment.
This optional service includes:

  • Fiber connection check-up
  • Unpacking and installation of your Fiber Box
  • Setup of the connection to your computer
  • Setup of the connection to your Apple TV 4K
  • Connection of your DECT telephone
  • Demonstration of the Salt.TV interface & service

Why do I need to indicate my mobile number when ordering?

In order to install your fibre optic connection, our service partner may need to contact you to make an appointment.
Therefore, it is important to provide a mobile phone number where our service partner can reach you quickly.

What is an "OTO ID" and where do I find it?

OTO stands for "Optical Telecommunication Outlet".
It’s the name given to the fiber connection installed in your home.
The number assigned to this connection – the OTO ID – is unique and allows to identify it precisely.
In order to activate your fiber connection, we need to know the OTO ID assigned to your home.

If your home is already connected to the optical fiber network, you should normally also have an optical telecommunication outlet (OTO).
If you are not sure whether this plug exists, your building management or the previous tenant should be able to provide this information.

The OTO is usually located in the living room, next to the main telephone outlet.
Your OTO ID corresponds to the number printed on the outlet.
As a rule, the OTO ID begins with A or B and uses the following format: A.XXX.XXX.XXX.X.

Important: Even if a building is connected to the fibre network, not necessarily all households are equipped with an optical fiber outlet.
Therefore, it might be necessary to install one to begin with.
Should this be your case please specify so when ordering and we will send an electrician to install one at your place.

How can I benefit from the offer “2 months of Salt Fiber subscription fees refund” to avoid double subscription fees?

- Please submit your refund request only after the activation of your Salt Fiber services.
- Make sure the last 1 or 2 invoices from your previous operator cover the same period of time as your first Salt Fiber invoices.
- Send us the copy(s) of the invoice(s) of your previous operator by e-mail to: fiber.2@salt.ch.
- We will assess your request in the following days.

Number portability

Can I keep my existing fixed line number and how can I make the request?

Yes, you can keep your existing number.
As soon as you have ordered Salt Fiber, please submit your transfer request in "My Account".
Please note that your fixed phone number can only be transferred within 20 working days after the cancellation of your previous contract.
Please submit your request exclusively via "My Account" as any documents sent by post will not be considered.


What is the minimum contract duration for the Salt Fiber subscription and are there any cancellation fees?

There is no minimal contract duration.
The contract can be cancelled at the end of each month with a notice of 60 days.
The following cancellation fees apply:

  • In case of cancellation during the 1st month a maximum fee of CHF 198.- will be applied.
  • Then the cancellation fee decreases by CHF 6.- per month.
  • After 33 months no cancellation fee is applied.

Which contracts do I have to terminate if I want to switch to Salt Fiber?

After ordering your Salt Fiber offer, you will need to cancel the contract you have with your current provider.
You can download the cancellation letter from our website here.
Please note:

  • Before cancelling please check the terms and conditions of your current contract (notification period and the early termination fees).
    Should you have any question with this regard, please contact your current provider directly.
  • If you want to make sure you will have no early termination fees to pay, please indicate your current contract end date as wish date for the Salt Fiber activation when ordering.

How many Apple TV 4k can I use?

You can order up to 5 Apple TV 4k.
The Apple TV 4k can be connected to the router via Wifi or cable.

To whom belongs the equipment and what happens with it at the end of the contract?

Salt Fiber Box:
The Salt Fiber Box (device and accessories) remains the property of Salt during the whole contract duration.
At the end of the contract, you have to return the whole equipment (including the original packaging) undamaged to Salt within 30 days.
If you fail to return the material - or if you return it damaged -, a compensation fee of maximum CHF 199.- will be charged (details ref. Product & tariffs brochure / Return of equipment).

Apple TV 4K Box:
The first Apple TV 4K Box is included in the Salt Fiber offer.
If you terminate the contract within the first 12 months, you have to return the TV box (incl. accessories) to Salt or pay a fee of 99.95 CHF.
After 12 months the TV box & accessories become your property and you can keep them in case of contract cancellation at no additional cost.
You can purchase up to 4 additional Apple TV 4K Boxes from Salt at the price of CHF 187.95 / box.
They are your immediate property and you can keep them in case of contract cancellation at no additional cost, independently of the cancellation date.


I move house, how do I need to proceed?

In the event of a move, you need to cancel your current Salt Fiber contract and place a new order for your future address.
The activation fee of CHF 99.95 will be applicable again.
However, Salt will reimburse you CHF 50.- on your first invoice to reduce the relocation costs to CHF 49.95.
(Please check if Salt Fiber is available at your new address on fiber.salt.ch).
Call the Salt Fiber Customer Service (0800 700 500) and place a request for move including the date.
Our Customer Service will terminate your current contract at the desired date.
It is your responsibility to place a new order for the future address.
Make sure you order in time taking into account the activation period, respectively the availability of your connection, i.e. of your OTO number.

After your order is completed, you will receive a new Salt Fiber Box and - if you have selected Salt TV - also a new Apple TV 4K.
Once the connection at your previous address is deactivated, you will have to return all associated equipment.
However, you can benefit from our special offer and keep the Apple TV 4K at the preferential price of CHF 99.95.
You would thus get 2 Apple TV 4K for only CHF 99.95 (the list price is CHF 187.95 per piece, which means you save CHF 275.95).
If you move house 12 months after signing the contract, you may keep your first Apple TV 4K free of charge. Hence, you will benefit from 2 Apple TV 4K for CHF 0.- (i.e. a saving of CHF 375.90).
Any additional Apple TV 4K you might have bought belongs to you and, consequently, no fee is required.
Finally, please note that the cancellation fees of your current contract will only be refunded once your new contract is active.

Can I use an optical fiber router from a different provider?

  • Reconnect the fiber into the OTO plug on the correct number (port 1 or 2; this information was sent to you by e-mail.)
  • Gently pull on the fiber cable to ensure that the cable is properly inserted. You should feel a slight resistance. (See video Salt Fiber Box - Cable check).
  • Make sure the small blue lever is pulled upwards. (See video Salt Fiber Box - Blue lever).
  • Make sure the grey connector (looks like a USB stick) is in place and cannot be removed. If the connector can be easily removed, it is incorrectly inserted and is not locked by the blue lever.

  • Plug the fibre cable into the grey connector.
  • Check the connection by pulling the cable slightly. If the grey connector comes out, repeat the previous step.

This will be needed to download the applications Salt.tv and Salt.video.

How can I connect my Apple TV 4K with my Home Cinema?

Can I subscribe to Sky via Salt TV?

You can subscribe to Sky (Sport or Show) only on their own website and not through the Salt TV application.
During the registration process on the Sky website, you will be requested to enter your voucher. This means that Sky will have recognised you as a Salt customer.
Subsequently, you will be able to switch from Salt TV to the Sky app with the Sky login credentials.


How can I access the VOD service?

You can access VOD using the Salt.video application on your Apple TV 4K.
The application needs to be installed from the AppStore.

Can I watch movies from my external USB disk or media server?
