How much am I charged for data roaming usage when my included volume is used up?

If you run out of data, you will be redirected to a page offering additional data bundles, valid 30 days after activation.
See Roaming.

Without any option or additional data bundle you may be charged up to 15.-/MB, depending on the travel zone you visit. Find out the details here: Tariffs abroad.

In this case, you will not be charged beyond the set limit. You can change these limits in → Subscriptions → Configuration (private customers) or in (Business customers).

What other precautions can I take to avoid roaming data usage?

There are several ways to minimize your costs when traveling abroad:

  1. Use a subscription with data included (unlimited or not) abroad like Europe XXL.
  2. Use data packages. See
  3. Reduce roaming costs by setting a limit. To do this, go directly to → Subscriptions → Configuration (private customers) or (Business customers).
  4. Deactivate the use of data abroad either in your phone's settings or on the network (contact our customer care for this).
    On the Samsung S7 for example, the “smart network switch” function must also be turned off. Some Android devices also feature a “data saver” function, which the user must activate.
    To prevent any further risk, the following functions should also be deactivated:
    • Wi-Fi Assist (iPhone)
    • Download booster (Samsung).

Receiving messages and calling your Voicemail with Salt domestic network is free.

In order to avoid these charges, we advise you to deactivate your voicemail before your trip. See How do I deactivate my Voicemail and reactivate it again?

Paid services

What are value added services (VAS)?

Value-added services numbers are used by companies to provide and charge services through a number.

In Switzerland, value-added services are usually starting with 08 or 09 (0800 are however free of charge).

You will find more information on Individual number allocation on the website of the Federal Office of Communications OFCOM.

On your Salt bill, calls to VAS numbers are displayed in the «Value-added services» section.

How can I deactivate a premium SMS/MMS service (value-added service)?

Find the short number of the value-added service in question on your detailed bill (My Account → Bills).

Then go to the page Search for short number* and use the indicated keywords to deactivate the service(s):

  • To deactivate one specific service:
    STOP [name of the service] to the short number of the service provider.
  • To deactivate all services of a specific service provider:
    STOP ALL to the short number of the service provider.
  • To block access to all adult services via your connection** (independently of the service provider):
    BLOCK ADULT to 5155.
  • To block access to all premium services via your connection** (independently of the service type and provider):
    BLOCK ALL to 5155.

Please note: You will no longer have access to any premium service at all and will no longer be able to use your mobile phone for service payments (e.g. Selecta vending machines, parking tickets etc.).

* You can search by provider name or by number.

** Blockage on Salt network level.

On my invoice roaming communications (calls, SMS or MMS) to one or several unknown number(s) are listed. What does this mean?

When you make roaming communications, you are connected to one of the mobile networks in your host country.

For invoicing purposes, operators in some countries may replace some destination numbers with generic numbers.

This is often the case for communications to service numbers, hotlines or value-added service numbers etc.

France Telecom, for example, systematically replaces all short numbers with the generic number +333000 on their invoices.)

Sometimes an operator has simply not registered the destination number and, therefore, indicates a generic one. Sometimes it is possible to find the real destination number on a search site of the country you travelled to (e.g., .fr, .es, etc.).

So, basically, the issue is not linked to any billing error but to the invoice display.

You can find all information about the details of your bill on this page.

What types of value-added services can I block?

You can block the following value-added services:

  • Premium Business
  • Premium Information
  • Premium Adult

Protection and abusive calls

Does Salt protect me from unsolicited marketing calls?

Salt protects you by default from unsolicited marketing calls. By activating the filter against unwanted advertising, you are protected against unsolicited advertising calls in the best possible way; however, it may happen that certain calls of this nature are still carried out.

However, if you would like to receive such calls, then you could deactivate the filter by selecting the option "Authorize marketing calls" in My Account → Subscriptions→ Options. If you are a Business customer, go to My Business Account, in the "Options" section of your subscription and choose the option "Authorize marketing calls".

How can I protect myself against fraudulent communications such as Spoofing, Phishing or scam-calls?
  • Do not answer calls from unknown numbers.
  • Block unknown and unwanted calls.
  • Do not provide personal information (especially sensitive financial information) in response to an incoming call.
  • Do not disclose your mobile phone number on websites or forms unless it is mandatory required.
  • Never call back callers with unknown numbers who hang up immediately or suspicious numbers in general.
