9 Best eSIM for Switzerland: Cheapest Data + the EU Trap
Drive from Munich to Zurich and your SIM can leave the roaming zone with no warning, then bill you out-of-zone rates all week. Switzerland sits outside the EU and the EEA, and that catches almost everyone. Here are nine eSIMs ranked, and the ones that cross the border with you.
September 10, 2026
Maya Mobile
- 5GB daily high-speed allowance
- 3 Mbps after daily limit
- 5G coverage with hotspot included
GigSky
- 180-day validity window
- Free 500MB starter plan
- Ideal for repeat Switzerland trips
Switzerland is the dearest country in Europe for almost everything. It is also one of the cheapest places on earth to buy mobile data.
Ten gigabytes here costs $6.13 from AlpineSIM and $7.80 from eSIMX. Forty gigabytes costs $12.99 from GoMoWorld, the travel eSIM run by Ireland’s national phone company.
A flat white in Zurich costs more than ten gigabytes of Swiss data. Nobody sees that coming, and almost nobody plans for it. Which is why so many visitors land on a three gigabyte plan and spend the week counting every map.
The other thing nobody plans for is the border.
Switzerland is not in the European Union, and not in the EEA either. The roam-like-at-home rules that let a French or German SIM work across twenty seven countries stop dead at Basel.
Some Europe travel eSIMs cover Switzerland and some do not, and the answer is buried in a country list rather than written on the front of the plan.
Meanwhile the country is small enough that a day out in Como, Chamonix or Konstanz takes you out of your plan and back again before lunch.
We ranked nine plans to find the best eSIM for Switzerland in 2026. On price per gigabyte, on plan shape, on what happens when your data runs out, and on which ones survive a day trip into Italy. Two of the nine are Swiss companies. All prices are before any code.
Top 3 eSIMs for Switzerland
Bottom line: buy GoMoWorld for the cheapest gigabytes here, from a company that actually owns a network.
Buy AlpineSIM if you want the lowest ten gigabyte price and a six month window. Buy Yesim if you want a Swiss company, unlimited plans and a VPN built in.

| Jetpac | $7.00 / 4d | $9.00 / 1d | $11.00 / 1d | $40.00 / 30d | $34.99 / 40GB / 30d | $0.73 (unlimited 30d) | none held |
| Truely | $3.99 / 30d | $12.49 / 30d | $18.99 / 30d | $30.49 / 30d | 5GB/day unlimited, $28.91 / 7d | $1.52 | none held |
Look at the 10GB column, then look again. AlpineSIM charges $6.13. Truely charges $18.99.
Same ten gigabytes, same thirty days, same three Swiss networks. That is a 210% gap, and what the dear end buys you is a nicer app and a no-expiry option. Not better signal.
Switzerland has three networks and one clear winner
Swisscom is the best network in the country, and it is not close. In the nPerf yearly report for 2025, measured up to January 2026, Swisscom scored 108,624 points. Salt got 99,074 and Sunrise got 97,923.
On 5G download speed Swisscom hit up to 271 Mb/s, about 32% faster than Salt at 201 Mb/s. If you are heading up into the Alps rather than staying in Zurich, this is the network you want under your plan.
Salt comes second, and it runs it very close in the cities. It has spent heavily on fibre and its city 5G is strong. Coverage thins faster than Swisscom’s once you start climbing.
Sunrise came third in the same tests. It is its own listed company again after Liberty Global spun it out. It has broad coverage and good prices for people who live there, which matters more to them than to you.
Two things follow for a visitor. Swiss coverage is superb almost everywhere, including cable car stations, ski areas and mountain villages, because tourism is the economy and the networks know it. And almost no travel eSIM will tell you which of the three you are on. So on most trips, the shape of your plan matters more than the network behind it.
The EU trap, and why it costs more here
This is the bit that saves people money, so it gets its own heading.
Switzerland sits outside the EU and outside the EEA. The rule that lets an EU SIM work at home rates across the bloc does not reach here.
Drive from Munich to Zurich and you can leave the roaming zone with no warning at all, then start paying out-of-zone rates on the same SIM you have used all week.
Travel eSIM sellers each made their own call. Some Europe packs take in Switzerland and some cover the EU only, and the country list is where you find out. GoMoWorld’s Europe pack has the words “incl UK and Switzerland” right in the title, which is the clearest label on this page.
Maya Mobile’s plans are global, so the question never comes up. With everyone else, read the country list line by line before you pay.
And the country is small, so borders are everywhere. Basel touches France and Germany. Geneva has France on three sides.
Lugano is forty minutes from Como. Chamonix, Konstanz, Milan Malpensa and Innsbruck are all easy day trips, and every one of them takes you out of a Switzerland-only plan.
Three ways to handle it.
The 9 best eSIMs for Switzerland
Ranked on price per gigabyte, on how long each plan lasts, on what happens once you hit the cap, and on whether the plan crosses a border with you.
No code held, and you hardly need one at these prices.
GoMoWorld is the travel arm of eir, Ireland’s national phone company. That makes it one of very few brands here that owns a network rather than renting one. It shows in the prices, which are the lowest on this page by a distance.
4GB for 7 days at $4.99. 40GB for 30 days at $12.99. 75GB at $24.99. 500GB at $34.99. The 40GB works out at $0.32 a gigabyte. The 500GB works out at seven cents.
The Europe pack is the other reason to be here. It is sold as Europe including UK and Switzerland, in the same four sizes at the same four prices. So a Zurich, Milan and Munich trip needs one purchase instead of three.
Nobody else here spells out the border problem and then solves it for the same money.

No code held. AlpineSIM’s shop prices already include its standing 10% offer.
AlpineSIM sells itself on bringing Swiss standards to travel eSIMs. Whatever you make of the branding, the price ladder is striking. 1GB for 7 days at $0.82. 5GB for 30 days at $3.40. 10GB at $6.13. 20GB at $11.71. 50GB at $24.27. There is also a 50GB with a 180 day window at $31.41, the cheapest long-life plan on this whole page.
That 10GB at $6.13 is the number to remember. It is $3.66 cheaper than GigSky, $4.87 cheaper than Ubigi and $12.86 cheaper than Truely, for the same data on the same masts. For a week of trains and cable cars, it is the plan.

Yesim was set up in 2019 by Dmitri Verbovski and Max Pankratov, and its head office is in Baar, in the canton of Zug. It passed one million users in 2025, works through deals with more than 800 carriers and roaming brokers, and it is the only brand here that is actually Swiss.
Buying a Swiss eSIM from a Swiss company is a small pleasure, and the product holds up.
Fixed plans run 1GB for 30 days at $2.90, 5GB at $11.15, 10GB at $18.59, 20GB at $25.56 and 30GB at $32.54. There is also a 500MB day plan at $0.52 for a layover.
Unlimited runs from one day at $3.49 up to eighty days, under a fair use policy. The app installs the eSIM for you, comes with a VPN built in, and sells add-on phone numbers, which nothing else here does.

Code ESIMX10 takes 10% off.
eSIMX prices Switzerland like a local network. 5GB for 30 days at $4.80. 10GB at $7.80. 20GB at $13.80. 30GB at $18.80. All on 5G.
The daily buckets are the interesting part: 2GB a day for 3 days at $3.80, 7 days at $6.90, 15 days at $14.80 and 30 days at $28.80. That works out at $0.48 a gigabyte if you use what you buy.
Two gigabytes a day covers maps, the SBB app, messages and an evening of streaming.
The daily shape suits a trip where you use roughly the same amount each day. For a fortnight of skiing, $14.80 covers the lot.

Maya Mobile sells global unlimited plans that cover Switzerland along with everywhere else. What earns it this spot is the slowdown speed. 5GB a day at full speed, then 3 Mbps, rather than the 1 Mbps most of this market drops to.
Three megabits still streams video, holds a call and loads a road map at the top of a pass. 7 days is $19.99, 14 days is $27.99 and 30 days is $49.99, all on 5G, with hotspot included.
Because the plans are global, the border problem simply goes away. Zurich, Como, Chamonix and Munich all sit inside one plan.
The trade is that Maya sells nothing small, so a two day layover is better off with Yesim or eSIMX.

Code ESIMADVICE15 takes 15% off.
GigSky’s edge here is time rather than money. 20GB with a 90 day window at $16.99 and 50GB with a 180 day window at $33.89 let one purchase cover a February ski trip and a July hiking trip. Its 10GB for 30 days at $9.79 is fair without being cheap, and there is a free 500MB plan when you sign up, with no card needed.
The daily buckets at $24.49 for a week are poor value next to eSIMX, and there is no unlimited tier.
Buy GigSky for the long windows and the free starter, not for the everyday plans.

Ubigi is the retail arm of Transatel, owned by NTT, and its unlimited plans are the most sensible after Maya’s.
20GB for 7 days at $24.00. 30GB for 15 days at $39.00. 60GB for 30 days at $59.00. Each one carries on at 2 Mbps once the allowance is gone.
Fixed plans are decent too: 10GB for 30 days at $11.00, 20GB monthly at $14.00 and 50GB for 30 days at $34.00, all on 5G.
It has slipped down this page because AlpineSIM, eSIMX and GoMoWorld undercut it hard on fixed data. The reason to still look is that 2 Mbps floor, if you want a fixed number with a safety net rather than a daily cap.

Jetpac is the travel brand of Circles, and it throws in things nobody else here bothers with. Free airport lounge access when your flight is over an hour late.
A free VPN trial. And emergency hotlines that keep working even when your data is spent.
In a country where Rega and 112 matter, that last one is worth having.
The plans are mid priced. 30GB for 30 days at $29.99 and 40GB at $34.99 are the value lines. The single day plans at $9.00 for 5GB and $11.00 for 10GB suit a Zurich Airport stopover.
Unlimited runs 3GB a day then 1 Mbps, from $12.99 for 3 days up to $65.99 for 30. The oddity is that 20GB costs $40.00 while 30GB costs $29.99, so never buy the 20GB.

Truely’s fixed plans are the dearest here, at $18.99 for 10GB and $30.49 for 20GB over 30 days. What it sells that nobody else does is data that never expires: 1GB for $4.99, 5GB for $15.49, 10GB for $24.99 and 20GB for $40.49, none of which ever run out of time.
Buy ten gigabytes, use four this winter, and the other six wait for the summer.
Unlimited runs 5GB a day at full speed, then 512 kbps, from $4.72 for a single day up to $74.87 for thirty. Five gigabytes is a generous daily cap, and 512 kbps is a harsh floor, so it suits people who never get near the limit. Everything is 5G.

Why your signal dies on Swiss trains?
This catches people out more than the mountains do. You board a smart Swiss carriage in Zurich, the view is stunning, and your phone loses everything.
The cause is the windows. Modern train glass has an ultra thin metal coating that roughly doubles how well the carriage holds its heat. The same coating blocks mobile signals from getting through. It is a physics problem, not a network problem, and it happens on some of the best covered railway in the world.
The Swiss have built a fix. A lab at EPFL working on solar energy and building physics made a portable laser that etches tiny lines into the metal coating, so mobile signals pass through while the heat stays in. A spin-off called nu glass turned it into a product.
It treats one pane in about 15 minutes and a whole railcar in hours, and it has been tried on a Swiss Federal Railways carriage. The other fix, boosters on board, eats up to 700 watts per railcar and needs replacing every time wireless standards move on.
Until every carriage is treated, plan around it. Download your offline maps. Save your route in the SBB app before you board. And treat a long panoramic run as reading time.
Where the signal really does die?
High alpine passes. The Furka, Grimsel, Susten and Nufenen roads all have stretches with nothing, especially on the north facing hairpins.
Deep side valleys. Val Müstair, the upper Lötschental and the back of the Val de Bagnes all go quiet where the walls close in, even though the resort at the end of the road is covered.
Inside the long tunnels. The Gotthard Base Tunnel and the Lötschberg run for tens of kilometres, and coverage inside is never a given.
Glacier ground above the lift stations. Cable car stations and pistes are covered properly. Walk off the marked area on the Aletsch or above Zermatt and it goes fast.
Everything else is superb. Every city, every lakeside town, almost every ski village.
How much data do you need in Switzerland?
A long weekend in Zurich or Geneva runs about 2 to 3GB. AlpineSIM’s 3GB for 30 days at $2.29 covers it for the price of a tram ticket.
Every eSIM Switzerland plan on this page is data only, apart from Yesim’s add-on number, so size it for maps, timetables and messages rather than calls.
Setting up before you land in Zurich or Geneva
Check your phone first. Dial *#06#. If an EID shows up next to the IMEI, your phone takes an eSIM. If not, our eSIM compatibility check covers your options.
Install on home wifi. Never on airport wifi, and never in the air. On iPhone go to Settings, Mobile Service, Add eSIM.
On Android go to Settings, Network and internet, SIMs, Add eSIM. The full walkthrough is in how to install an eSIM.
Then, before you land:
Two local notes. The money is the Swiss franc. Cards work everywhere, and euros are taken grudgingly at poor rates.
The dialling code is +41, emergency services answer on 112, and 1414 reaches Rega direct if you are up in the mountains.
FAQ’s
Does my EU SIM work in Switzerland at home rates?
Usually not. Switzerland sits outside the EU and the EEA, so roam-like-at-home does not apply, and most EU networks treat it as a separate zone. A few tariffs near the border throw it in as a goodwill gesture. Assume it is out, and check your provider’s zone list before you drive.
Which Swiss network is best?
Swisscom, on the published tests. In the nPerf yearly report for 2025 it scored 108,624 points against Salt’s 99,074 and Sunrise’s 97,923, and its 5G reached up to 271 Mb/s against Salt’s 201 Mb/s. In real life all three are strong in the cities, and Swisscom pulls ahead in the mountains.
Why does my phone lose signal on Swiss trains?
Because of the windows, not the network. Modern carriages use metal-coated glass to hold their heat, and the coating blocks mobile signals. A Swiss laser treatment that etches tiny lines into the coating fixes it without losing the heat, and it is being rolled out. Plenty of carriages are still untreated.
Is Switzerland really cheap for mobile data?
For travel eSIMs, yes, and it is one of the cheapest markets anywhere. Forty gigabytes costs $12.99 from GoMoWorld and ten gigabytes costs $6.13 from AlpineSIM. Swiss home phone contracts for residents are a different and much dearer story, and that is where the country’s reputation comes from.
Is Yesim actually Swiss?
Yes. Yesim was set up in 2019 by Dmitri Verbovski and Max Pankratov, with its head office in Baar, in the canton of Zug. It passed a million users in 2025 and works through more than 800 carrier and roaming partnerships worldwide. AlpineSIM uses Swiss branding, and GoMoWorld is owned by eir, the Irish national carrier.
Should I buy a Swiss prepaid SIM instead?
Rarely worth it. Swiss prepaid tourist deals are priced for residents rather than visitors, they start well above what the eSIMs here charge, and you will need ID to register. At $6.13 for ten gigabytes, there is no queue worth joining.
Our verdict
Buy GoMoWorld. Forty gigabytes for $12.99, from a company that owns a national network, is the best price on this page by a mile. And its Europe pack carries Switzerland and the UK in the title, which makes the border problem disappear for the same money.
Buy AlpineSIM if your trip is a week or less and you want the cheapest ten gigabytes in Europe. Or its 50GB with the 180 day window if you come back every season. And if you would rather your Swiss data came from a Swiss company, Yesim in Baar is the one, with a VPN built into the app.
