If the option is installed, then it will be automatically activated the first time calling services (incoming or outgoing call, SMS or MMS) or mobile Internet are used abroad, and the usage charge will be billed at the same time.
For example: The travel day pass option is installed. The first use abroad is at 9 a.m.; the option is activated and the included services can be used until 11:59 p.m. (CET). If the option is uninstalled, then calls, SMS and mobile Internet abroad will be billed at the standard roaming rate.
The included services can then be utilized up to midnight of the same calendar day. The usage charge is only billed if the roaming services (incoming or outgoing calls, SMS or data connection abroad) are not already free based on the mobile subscription or a previously subscribed roaming option.
If the included data volume of 100 MB per calendar day has been used up and no other roaming data credit is available, data connections are blocked until midnight.
To continue surfing:
Add data volume with a travel data option
Deactivate the travel day pass and continue surfing at the standard roaming rate
The data consumption can be viewed at cockpit.sunrise.ch; an information SMS message is sent when the credit is used up.
