Frequently asked questions.

How can I activate the service?

SBB FreeSurf offers you as a rail passenger free Internet access with your existing mobile phone price plan (subscription or prepaid offer).

  • As a Salt or Sunrise customer, you will need a standard smartphone (Android or iOS).
  • You can download the SBB FreeSurf app from the App Store (Apple) or the Play Store (Google).
  • At your first connection, you need to complete a one-off registration and accept the GTCs.
  • Activate «Bluetooth». The Bluetooth connection uses a relatively large amount of power (you might want to take your charging cable with you).
  • Get on a SBB long-distance train.
  • Open the app SBB FreeSurf. The «Mobile data» feature has to remain active in order to connect to your operator's network.
  • Select «Connect».
  • You will receive a confirmation message from your provider and have unlimited access to SBB FreeSurf during your train journey.
  • When leaving the train or if you disconnect, you will receive a message confirming that the free service has been deactivated.
How much does SBB FreeSurf cost?

The usage of SBB FreeSurf is free of charge for you.
SBB takes on the mobile network provider connection costs during the train journey.

How can I ensure that SBB FreeSurf won’t use mobile data before I connect?
  • iOS: In settings, deactivate “background updates” for all apps so that no unwanted data volumes are used in the background.
  • Android: In settings, deactivate “data saving” for all apps so that no data volumes are used in the background.
  • Before getting off the train, turn off the data connection without waiting for the confirmation SMS from Salt (notification that from now on, data usage is payable again / is deduced from your mobile subscription's data allowance).
Is data protection for passengers safeguarded?

Yes. SBB AG complies with the data protection regulations.

SBB guarantees that they are not tracking your movements and that the location data is deleted straightaway.

This data is used solely to determine the duration of data use for billing.

Customers expressly agree to the use of data before they use the free Internet access (we use the same approach for Free-WLAN).

The telecommunications operators have no passenger location data, only data on the period of use.

The performance of the SBB FreeSurf service is poor. What is the reason?
  • iOS: In settings, deactivate “background updates” for all apps so that no unwanted data volumes are used in the background.
  • Android: In settings, activate “data saving” for all apps so that no data volumes are used in the background.
  • Before getting off the train, turn off the data connection without waiting for the confirmation SMS from Salt (notification that from now on, data usage is payable again / is deduced from your mobile subscription's data allowance).
