Switzerland travel guide: mobile data, networks and what's on

What the network is actually like

Switzerland has 4G and 5G almost everywhere people live. SBB is fitting signal repeaters in its coaches, and coverage holds through the Gotthard Base Tunnel. In the mountains signal can come and go within a few hundred metres, and the Glacier Express runs through 91 tunnels. About 80 stations have free SBB wifi.

This eSIM: up to 3G, 4G, 5G, onSunrise, Salt. Each plan on the Switzerland page says which of these it uses.

How much data you'll need

10GB covers two weeks. Most of it goes on maps and the SBB Mobile app, which sells tickets for train, bus and boat and pushes delay alerts.
