Once travel day pass data is installed, you automatically surf for CHF 1.90 per day (100MB) when you start surfing abroad. Young customers have unlimited WhatsApp data volume in Region 1. VoIP (calls and video calling through WhatsApp) is excluded
When the 100MB is used up, data roaming will automatically be blocked. This way, your only cost for roaming data per day is CHF 1.90.
