Best eSIM for Switzerland (2026), Ranked

The one to get if coverage matters.

Swisscom is the best network in Switzerland. Full stop. Opensignal gave them “Best Network” and top marks for Coverage Experience in their March 2025 report. If you’re going anywhere outside a major city (trains through the Alps, hiking near Zermatt, driving through valleys) Swisscom is the only network you can count on.

Their tourist eSIM includes unlimited data (capped at 50 Mbit/s, which is plenty), unlimited calls within Switzerland, and a Swiss phone number. You order online and it works immediately.

Plan	Price	Data	Calls & SMS
7 days	CHF 20	Unlimited (50 Mbit/s)	Unlimited within CH
15 days	CHF 40	Unlimited (50 Mbit/s)	Unlimited within CH
30 days	CHF 65	Unlimited (50 Mbit/s)	Unlimited within CH
90 days	CHF 150	Unlimited (50 Mbit/s)	Unlimited within CH

CHF 20 for a week of unlimited everything on the best network in the country. That’s roughly US$22. Getting hit with one day of roaming charges from your home carrier would cost you more than that.

• Pros: Best coverage by a clear margin, unlimited data and calls, Swiss phone number, instant activation
• Cons: Switzerland-only (useless once you cross the border), priced in CHF

Cheapest option that actually works.

Saily is straightforward: buy a data pack, install it, go. No frills, clear pricing, decent service. It’s data-only (no calls, no SMS) but that’s fine for most travelers who just need Google Maps and WhatsApp.

Plan	Price	Validity
1 GB	US$3.99	7 days
3 GB	US$9.99	30 days
5 GB	US$13.99	30 days
10 GB	US$22.99	30 days
20 GB	US$36.99	30 days

US$3.99 for a weekend trip. US$13.99 for a full week with plenty of data. Hard to argue with those numbers.

• Pros: Cheap, transparent pricing, easy app-based setup
• Cons: Data-only, no unlimited option, can’t match Swisscom’s rural coverage

Unlimited data if you don't want to think about it.

Holafly gives you unlimited data on Swisscom/Sunrise/Salt networks with 4G/5G support. You get 1 GB/day of hotspot sharing. The selling point is simple: you never run out, you never top up, you never do math.

About US$19 for 5 days of unlimited data.

Worth it if you’re working remotely, creating content, or the kind of person who streams video on the train. Overkill if you just need maps and messages. Get Saily instead and save the money.

• Pros: Truly unlimited, multiple Swiss networks, hotspot included, zero management
• Cons: Expensive for what light users need, data-only, 1 GB/day hotspot cap

Good if you genuinely don't know how much data you'll need.

Nomad starts at US$4.50 and their main feature is add-ons: you can buy more data without replacing the eSIM. That’s useful if you’re the type who might need 2 GB or might need 15 GB depending on how the trip goes.

For everyone else: just pick Saily or Swisscom and skip the decision fatigue.

• Pros: Cheap entry, hotspot included, flexible add-on system
• Cons: Smaller company, support is slower, not the best at anything specific

The only real option for multi-country trips through Switzerland.

Here’s the problem most people don’t realize: you book a train from Milan to Zurich to Paris, and your “Europe” eSIM stops working the moment you cross into Switzerland because Switzerland isn’t in the EU.

Sunrise fixes this. Their travel eSIM gives you unlimited data in Switzerland and 60 GB of high-speed data across 46 European countries. If your trip involves any cross-border movement, this is the one.

• Pros: Unlimited in Switzerland + 60 GB across Europe, Swiss calls/SMS, solves the EU gap
• Cons: Pricing less transparent than others (check Sunrise website), setup requires their app

Fine, but not the best at anything.

Airalo is the biggest eSIM marketplace. Plans start at €4.00 for 1 GB. The app is polished. It works.

But Saily is cheaper for the same thing, Swisscom is better for coverage, and Holafly is better for unlimited. Airalo isn’t bad. It’s just not the best option for Switzerland specifically.

• Pros: Wide plan selection, good app, large company
• Cons: Slightly more expensive than Saily, data-only, no unique advantage here

Don't bother.

Salt charges CHF 59 just for the eSIM. That’s almost three times what Swisscom charges for a full week of unlimited everything. Salt’s coverage is also the worst of the three Swiss networks, especially in mountains. There is no scenario where Salt makes sense for a tourist.
