Bug fixes and general improvements

User reviews

Swiss Only!

You must have a Swiss mobile number in order to use. Too bad.

Anti-foreigner

This app only works if you are a Swiss national or are willing to switch out your SIM card for a Swiss one which is totally unnecessary. No wonder the reviews are so low. Shocking approach to take. Get it sorted.

Not so friendly

Visitors usually buy data only esim so why make it inconvenenient for tourists to avail of the free wifi. In Japan, visitors can get free and uncumbersome wifi on bullet trains. Why not allow phone numbers where tourists come from?

Nice but only with Swiss phone number

Be nice to offer registration via email rather than phone only. Used the excellent SBB app throughout Switzerland recently but could not get access to the free wifi as travelling on a data only esim

Does not work

You’ll get error “FS-300” with message “SBB FreeSurf is available to customers of digitec, Quickline, Salt, Sunrise, Swisscom.” or your number won’t be accepted

I got this even when roaming on an eligible carrier.
