Will I have data on the Glacier Express and Bernina Express?

For much of the route, yes - both lines run through Graubünden with data around stations and open valleys. Signal naturally cuts out in the many tunnels and remote high sections, so download anything essential before you depart.

Is there coverage while skiing at St. Moritz or Davos?

Across the main resort areas and villages, generally yes - both are well served. Data thins on far glacier runs, high off-piste bowls and the most remote lifts, so save your piste map offline for the day.

Good to know in Graubünden

The Bernina and Glacier Express are the whole point of Graubünden - but they pass through deep gorges and long tunnels, so download your seat map, playlists and photos before boarding rather than relying on signal en route.

Best time to visit Graubünden

December to March for skiing at St. Moritz, Davos and Arosa; June to September for hiking the Engadine, the national park and the scenic rail routes.

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Across the region

Where you'll lean on data in Graubünden.

St. Moritz

The Engadine resort has strong village coverage for lift and restaurant bookings, thinning across the surrounding high lakes and glaciers.

Davos

Reliable data across town - reinforced during the World Economic Forum - with weaker signal on the outlying Parsenn ridges.

Swiss National Park (Zernez)

Switzerland's only national park has patchy-to-no coverage on its protected trails, so download maps at the Zernez visitor centre first.

Chur

Switzerland's oldest town and the cantonal capital enjoy steady 4G/5G for planning onward Bernina and Glacier Express journeys.

How much data for Graubünden

Balanced 3-5 GB covers a week of maps, hut bookings and photo sharing; go Unlimited if you'll stream from the long train rides or video-call from a ski chalet.

Coverage in Graubünden

Coverage is strong in Chur, St. Moritz, Davos and the resort towns, but realistically thins on high passes, deep rail tunnels and the protected trails of the Swiss National Park.
