How much does SBB FreeSurf cost?

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.
