What data actually costs in Switzerland

EU roaming does not save you here

Switzerland is in neither the EU nor the EEA, so roam-like-at-home does not apply. Some European operators fold Switzerland into their roaming zone voluntarily and some charge painful per-megabyte rates for it, and the two look identical until the bill arrives. Check your own contract's country list before you assume anything — this is the single most expensive assumption a European visitor can make.

If you are not covered, you are buying something. Here is what it costs.

The floor is $0.90 per gigabyte

Switzerland is not a cheap market, but it is cheaper than it looks from the small plans. The good rate sits only at the very top of the ladder.

Look at the two largest Airalo rows. Going from 20 GB to 50 GB costs $9 and gives you 30 GB more. That is the sharpest step-up we hold for any European country, and it means the 50 GB plan is the right buy for anyone who would otherwise consider 20 GB, and probably for anyone considering 10.

Saily's prices were read off its own site on 16 August 2026 and are verified alongside Airalo's, which were read on 13 August. The two track each other almost exactly at the smaller sizes — Saily's 5 GB is a cent under Airalo's, and its 10 GB at $22.99 a cent under Airalo's $23 — and then part company at 20 GB, where Saily's $36.99 is 99 cents above Airalo's $36.00. Cheapest at that size by a distance is Nomad's $25, read off its own site on 17 August 2026 — eleven dollars under Airalo. Saily's verified $3.99 for 1 GB over seven days is the lowest entry price on the board.

A note on duration. Airalo's 10 GB is $21.50 for seven days, $22 for fifteen and $23 for thirty. The extra window costs $1.50. Take it.

Unlimited, and when it stops being silly

Airalo's verified unlimited plans run $11.50 for three days, $18 for five, $25 for seven, $34 for ten, $46 for fifteen and $68 for thirty, and Nomad's verified plans match or undercut them at the four lengths it sells, at $11, $18, $25 and $33. Holafly's are verified and mostly a little dearer at matching lengths: $18.50 for five days, $25.50 for seven, $34.90 for ten, $46.90 for fifteen, $68.90 for thirty. Holafly does list a one-day unlimited at $3.90, which is the cheapest thing in the Swiss data at any size — useful for a single day's transit and nothing else.

Otherwise the metered plan wins comfortably. Fifteen days unlimited from Airalo is $46; 50 GB over thirty days is $45. You would have to burn more than 50 GB in a fortnight to come out ahead, which for most trips means streaming on a hotel TV via your hotspot.

Buying on arrival

Swiss prepaid SIMs need no ID at most retail outlets, so buying is quick. Swisscom and Sunrise SIMs are sold at Zurich and Geneva airports, in Migros and Coop supermarkets and in Sunrise stores. Tourist packages run CHF 15–25, roughly $17–28, and the airport price is about $20.

So a local SIM costs about what Airalo's 20 GB costs and more than double its 5 GB. On price alone the eSIM wins. There is one reason to buy locally anyway, and it is a good one.

Swisscom, altitude, and what we cannot promise you

Swisscom has the widest coverage in the country — mountain villages, ski lifts and rail tunnels included — and is the network to have for alpine travel. That is a fact about Switzerland's networks, not about any eSIM.

What we cannot do is tell you to get Swisscom through an eSIM. Airalo does not publish which Swiss network its Pilatus Mobile plans roam onto; Pilatus Mobile is a product name at checkout, not a carrier. Saily publishes nothing either — we read its site on 16 August 2026 and it names no operator for Switzerland or for any other country — and neither does Nomad, which corrects a listing this page used to carry against its rows. Holafly publishes nothing either — the three-operator listing this page used to carry against it came from our own data rather than from the seller. eSIMCard lists Swisscom and Sunrise in its own product listing, which we have never been able to confirm in either direction. Advice that depends on landing on a particular network is advice we cannot stand behind.

If your trip is alpine and signal genuinely matters, walk to a Swisscom counter at the airport and ask for Swisscom by name. That is the version of this advice that is actually followable.

Know the gaps either way: high-altitude ski runs and off-piste terrain above 3,000 m, the Matterhorn summit at 4,478 m, the Fiemme valley road and some remote hiking trails. Wifi fills most of the rest — hotels, cafés, all SBB InterCity trains, and fast unlimited wifi at the airports. Emergency calls connect on any Swiss network without an active plan.

Every Swiss plan we hold is listed on the Switzerland hub; how prices are checked is on how we test.
