Comparing Swiss SIM cards and travel eSIMs

Your EU roaming may stop at the border

This is the first thing to check and the thing most travellers get wrong. Switzerland is not in the EU or the EEA, so roam-like-at-home does not apply automatically. Some European operators bundle Switzerland in with their EU zone anyway; others put it in a surcharge band that can cost more per day than a whole travel eSIM. Look at your own tariff before you assume you are covered — the answer varies by operator, not by country.

If you are covered, buy nothing. If you are not, Switzerland is an expensive place to get this wrong, and the rest of this page is the arithmetic.

The local SIM: about $20, no ID, unknown allowance

Three networks: Swisscom, Sunrise and Salt Mobile. A tourist SIM at the airport runs about $20, and no ID is required — you buy it and it works, which is rarer in Europe than it should be.

From the original research, physical SIMs from Swisscom and Sunrise are sold at Zurich and Geneva airports, in Migros and Coop supermarkets and in Sunrise stores, with tourist packages priced at CHF 15–25, roughly $17–28.

What we do not have is the allowance. Nobody has recorded how many gigabytes that CHF 15–25 pack contains or how long it lasts, so we cannot put a cost per gigabyte against the eSIM table below, and we are not going to guess. Ask at the till. If the pack holds 20GB or more, it is competitive with anything here; if it holds 2GB, it is not.

What the eSIMs cost

Airalo's Swiss prices were read from its own site on 13 August 2026, and it sells the country under the package name Pilatus Mobile. Saily's were read from its own site on 16 August 2026. Nomad's were read from its own site on 17 August 2026. Those three are verified; the Holafly rows are indicative — collected, not read off the provider's checkout — so confirm before paying. eSIMCard's rows have been withdrawn: we read its own pages on 18 August 2026, found the figures we held were wrong, and could not store the real ones. See our eSIMCard page.

Saily and Airalo sit a single cent apart at 5GB and 10GB, with Saily just underneath, and then swap places at 20GB where Saily is 99 cents dearer. Both price lists are verified, so that is a real ordering rather than an artefact — and at the two smaller sizes it is also a distinction without a difference. Nomad's $25 is the one genuinely cheaper 20GB on the page, and it is a checked figure — eleven dollars under Airalo for the same allowance and month.

The bottom rows are the ones to notice, because they are the numbers most comparisons of this market miss. The verified 50GB over 30 days is $43.00 from Nomad and $45.00 from Airalo — 86 and 90 cents a gigabyte. Switzerland is a dear country for data by European standards, but the floor here is 86 cents, not the $1.40 or so you will see quoted, including on an earlier version of our own coverage.

At the other end, small plans are punishing: one gigabyte over three days works out at four dollars a gigabyte. For a week of maps, messaging and ordinary photo uploading, the verified 5GB month at $12.50 beats any one-gigabyte plan on the page.

Unlimited is worth a mention because Switzerland is where people ski, and skiing means video. Airalo's verified unlimited runs $11.50 for three days, $18.00 for five and $68.00 for 30. Holafly's verified equivalents sit slightly above at every comparable length, except the single day: $3.90 for 24 hours of unlimited, which nobody else here matches. Holafly does not support hotspot, though, so it is the wrong choice if a laptop or a second phone needs the connection.

The alpine coverage question

Swisscom is the operator with the widest reach into mountain villages, ski lifts and train tunnels, which is why alpine trips usually end up pointed at it. That is a statement about Swisscom, not about any eSIM.

An earlier version of this page recommended Holafly for remote alpine areas on the grounds that it runs across all three Swiss networks. We are not repeating that. The three operators came from our own data rather than from Holafly, whose country pages name no carrier for Switzerland or for anywhere else — so there is no network claim left to recommend on. The two-operator listing our data carried on some eSIMCard rows came from our own generated text — and the one this page used to carry against Nomad has gone, because Nomad publishes no host network anywhere. Airalo publishes no host network at all, here or anywhere, and nor does Saily — we read its site on 16 August 2026 and it names no operator in any country, so an older Swisscom and Sunrise attribution against its rows has been dropped.

If your trip depends on signal above the treeline, the honest advice is a local SIM on the network you have chosen — no ID needed — plus offline maps. Signal fails on high-altitude and off-piste runs above about 3,000 metres, near the Matterhorn summit, on the upper Aletsch Glacier and on some remote hiking trails regardless of what you bought.

So which one
