SBB FreeSurf

This is such a gimmick and scam. They will only offer free wifi if you buy eSIM from a selected swiss telecom companies. Most big companies have unlimited data plans within Switzerland so there is no point of saying that you offer free wifi on the trains. Shameful to falsely advertise this service for tourist by the one of the biggest train company. France trains for example have “truly free” wifi on long journey trains.

If you are aboard with eSim(data only) don’t bother to download since it only accepts swiss number when register as the first step. Even if you do have eSim with voice, you need to have a swiss number. Free wifi offering should be straightforward and works for any one whether is local or aboard. Such a big railway company can’t figure out how to make the process simple is a shame!!

There’s no way to register unless you have a Swiss phone number. They claim it works with eSIM but there’s nothing to do and it’s all dependent on a SMS confirmation. Don’t bother if you’re American. Just buy a travel plan through your provider at home. 5G works well almost everywhere.
