Is there mobile coverage up at the Jungfraujoch and in the valleys?

Villages like Grindelwald, Wengen and Lauterbrunnen are well covered, and there's even signal at the Jungfraujoch station. Coverage genuinely thins on high trails, glaciers and inside the long railway tunnels bored through the Eiger.

I'm hiking between villages — can I rely on my phone for maps?

On popular routes near the lifts, yes. But high-alpine trails above Mürren or around the Schynige Platte can lose signal, so download offline maps and your route before you set off from the valley.

Good to know in Interlaken

Mountain-railway tickets to the Jungfraujoch are expensive and time-slotted, and the summit is often clouded — check the Jungfrau webcams and book your slot on your eSIM the evening before to avoid paying for a view of fog.

Two simple ways to buy

Interlaken eSIM plans: unlimited, or by the GB.

Every Interlaken eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Interlaken — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

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.

Interlaken eSIM: your local data guide.

Interlaken is Switzerland's adventure capital, so you'll live on your phone here — booking Jungfraujoch trains, timing the Harder Kulm funicular, checking paragliding weather over the Höheweg or planning the day up to Grindelwald and Lauterbrunnen. An Interlaken eSIM keeps mountain-railway apps, maps and booking confirmations live from the moment you arrive between the two lakes.

One eSIM for Interlaken and all of Switzerland. It's the national Switzerland eSIM — from $2.15/day with unlimited data, working the same in Interlaken as it does the moment you leave it.

Landing at Zurich Airport (ZRH) — roughly two hours from Interlaken by train via Bern?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
