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 SBB-FREE).

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

Thanks to SBB FreeSurf you have access to the internet with the best possible transmission speed along the train route (depending on the availability and capacity of the mobile network). However, this depends on the mobile network coverage along the route and the number of people accessing the antenna at the same time. That is why on an empty train the transmission rate is better than on a fully occupied train.
