Let’s say, you arrive in Paris on Friday at 11:00…
When you start surfing (example at 11:10), travel day pass data (CHF 1.90) will be automatically activated, 100MB will be valid for 24 hours.
Friday at 19:30 – 100MB is used up: for full cost control, data roaming will be blocked until Saturday 11:10.
If you want to keep surfing, you can add another 100 MB for CHF 1.90 (valid until 11:10 on Saturday) via cockpit.sunrise.ch
Saturday 11:10 – 24 hours are over and your data allowance expires. A new 100MB allowance (valid for 24 hours) will be automatically activated when you start surfing again.
