Quick answer: Based on my own on-ground tests as a Swiss resident, Saily is the eSIM I would personally choose for Switzerland in 2026. I measured up to 370 Mbps download on Salt 5G with 0% packet loss, and setup took under 5 minutes. My recommended Saily discount code is TECH, which gives 15% off Saily plans, including Switzerland eSIMs and Saily Ultra.

Saily Switzerland: Pros and Cons
Pros | Cons |
|---|---|
Fast speeds in my Swiss tests: up to 370 Mbps on Salt 5G | No local Swiss +41 phone number; optional US phone number add-on only |
Worked on both Salt and Sunrise during my tests | Unlimited plans cost more than fixed-data plans |
Very easy setup before arrival in Switzerland | Exact local partner network can vary by location and roaming agreement |
Local Swiss prepaid SIMs can be cheaper for long stays | |
Hotspot support for laptop use while travelling | Not ideal if you need unlimited data with zero usage tracking |
Easy in-app top-ups and 80% usage notifications | Requires an eSIM-compatible phone |
Code TECH gives 15% off Switzerland eSIMs and Saily Ultra | A local Swiss prepaid SIM may still be better if you need a Swiss number or long-term local plan |
For most visitors, the pros clearly outweigh the cons. If you mainly need Google Maps, WhatsApp, hotel messages, train connections, streaming and occasional hotspot use, Saily is one of the easiest Switzerland eSIM options I have tested.
Why I Recommend Saily for Switzerland
Most "best eSIM" lists for Switzerland are written by people who have never set foot here. I have — for over 30 years. I tested Saily on-ground in the St. Gallen / Lake Constance region and across the Alpstein, with my Swiss SIM data fully deactivated, running Saily as my sole connection on an iPhone 15 Pro.
The result: 271–370 Mbps download on Salt 5G, 0% packet loss, idle ping of 36–39 ms. For a country with some of the densest, fastest mobile infrastructure in the world, that's exactly the bar an eSIM has to clear — and in my tests, Saily cleared it comfortably.
In my own tests, Saily connected to Salt and Sunrise in Switzerland, switching automatically to whichever was strongest at each location. Saily also describes its Switzerland eSIM as running on reliable local Swiss networks; depending on your location and Saily's roaming agreements at the time, the exact partner network may vary. That automatic switching — not having to think about which network I was on — was one of the most useful things about using it here.
I've lived in Switzerland for over 30 years, so I know what this network looks like at its best — on the Jungfraujoch at 3,454 m, in the Alpstein, in the cities. Saily held up against that baseline in every test I ran.
Real Test Setup
I'm Nico Dudli, a Swiss digital transformation consultant and tech author based in St. Gallen, Switzerland. I've tested Saily across 12 countries in Europe and Asia and compared it against Airalo and Holafly in my Saily eSIM review. Switzerland is my home — this is the one review where I can judge Saily against a baseline I know inside out.
Test method: Swiss SIM data off → Saily eSIM only → multiple speed tests across different locations and days, all publicly verifiable via Speedtest Test ID.
Saily Features That Matter in Switzerland
Before looking at the speed tests, it is worth understanding why I recommend Saily for Switzerland beyond raw download numbers. Fast mobile data matters, but for travellers, setup, security, hotspot support and easy top-ups are just as important.
Feature | Why it matters in Switzerland | My take |
|---|---|---|
Built-in web protection | Useful on hotel Wi-Fi, airport Wi-Fi, train station Wi-Fi and public networks | A strong extra benefit, especially because Saily comes from the Nord Security team |
Ad blocker | Helps reduce annoying ads and can save a small amount of data while browsing | Useful for travel research, maps, blogs and booking sites |
Virtual location | Lets you browse more privately and choose from 115+ virtual locations | Helpful if you care about privacy or want to access home content while travelling |
Optional US phone number add-on | Useful if you want a separate number for calls, texts, OTPs or travel sign-ups | Good extra feature, but it is a +1 US number, not a local Swiss +41 number |
Top-ups in the app | You can add more data without buying a new physical SIM or visiting a Swiss store | Very practical for longer Switzerland trips or heavy hotspot use |
80% data usage notification | Saily notifies you before your plan runs out, so you still have time to top up | Very useful in Switzerland, especially if you use maps, hotspot or streaming often |
Hotspot support | Lets you share your eSIM connection with a laptop or tablet | Important for remote workers, digital nomads and travellers booking trains or hotels |
30-day activation window | You can buy before departure and activate only when you connect in Switzerland | Ideal for travellers who want everything ready before landing |
One eSIM for multiple trips | You can keep using the same Saily eSIM and simply add new plans | More convenient than buying a new SIM or eSIM for every destination |
Global and regional plans | You can use Saily not only for Switzerland, but also for Europe or multi-country trips | Helpful if Switzerland is part of a longer Europe itinerary |
Works in 200+ countries | Useful if Switzerland is only one stop on a larger international trip | One of Saily's biggest advantages over local prepaid SIMs |
24/7 support | Support is available if something goes wrong during setup or connection | Important for travellers who do not want to troubleshoot an eSIM alone abroad |
Saily Ultra option | Adds global data, airport lounge access, fast-track service and Nord Security tools | Better for frequent travellers than for a simple weekend trip |
In short: I would not recommend Saily for Switzerland only because it was fast in my tests. The bigger advantage is that Saily combines travel data, security features, easy top-ups, usage notifications, hotspot support, optional US phone-number functionality and 24/7 support in one app.
Saily eSIM Switzerland Speed Test Results (2026)
Eight tests across different locations, iPhone 15 Pro, Salt 5G/LTE (St. Gallen / Lake Constance) and Sunrise 5G/LTE (Alpstein / Appenzell, Schwägalp):
Test | Location | Network | Download | Upload | Idle Ping | Packet Loss | Date | Test ID |

8 | Schwägalp — Säntis-Talstation | Sunrise LTE | 42.89 Mbps | 3.71 Mbps | 54 ms | — | 05.06.2026 | 7102578922 |
All tests publicly verifiable at speedtest.net via Test ID. Test location for Tests 3–6: Bogartenlücke, Alpstein (Appenzell Innerrhoden), approx. 1,500 m altitude. Speedtest server was the nearest available node (Gais / Buchs) — not the physical test location.
*Test 6 (Alpstein — Bogartenlücke, 5G, 09:37): 100.36% packet loss indicates a complete signal dropout, recorded at the start of the ascent before a stable 5G connection was established — typical in Alpine terrain during network transitions. By 09:40 (Test 5), the same 5G network delivered 65.25 Mbps with only 0.36% packet loss.
What These Speeds Mean for Travelers
Use case | Needed | Saily result |
|---|---|---|
Google Maps / Apple Maps | ~1 Mbps | ✅ Easily covered |
FaceTime / WhatsApp video call | ~3–5 Mbps | ✅ No issues |
4K streaming (Netflix, YouTube) | ~25 Mbps | ✅ Handled |
Laptop hotspot | ~20–50 Mbps | ✅ Comfortable |
Navigation during Alpine hike | ~1 Mbps | ✅ No issues (tested Bogartenlücke, 1,500 m, Sunrise LTE) |
Verizon / AT&T international day pass | ~$10–13/day | ❌ Avoid |
💡 Pro tip (from a Swiss local): Verizon TravelPass costs $12/day in Switzerland — $84 for a 7-day trip, with only 5 GB high-speed data before throttling to 3G. Saily's 5 GB / 30-day plan costs $13.99 total (~$11.89 with code TECH). Same data volume. Six times cheaper.
Option | Cost (7 days) | High-speed data | After limit |
|---|---|---|---|
Verizon TravelPass | $84 | 5 GB/day | 3G throttled |
Saily 5 GB / 30 days | $13.99 | 5 GB total | — |
Saily 10 GB / 30 days | $22.99 | 10 GB total | — |

Is Saily expensive for Switzerland? No — it's affordable by local standards. SBB occasionally offers slightly cheaper data, but setup is more complex and you lose global reusability. One Saily eSIM works across 200+ countries, which is what makes it the eSIM I keep coming back to for Switzerland specifically, not just a cheap one.

Why I Recommend Saily Over Airalo and Holafly
Provider | Best for | Switzerland pricing style | Security features | Hotspot | Phone number | My verdict |
|---|---|---|---|---|---|---|
Saily | Most travellers who want flexible data, easy setup and good value | Fixed-data plans plus unlimited options | Built-in web protection, ad blocker and virtual location | Yes | Optional US phone number add-on available in the Saily app | My first choice for most Switzerland trips |
Airalo | Travellers who want a simple fixed-data eSIM | Fixed-data plans | No major built-in security suite | Usually yes | Usually data-only, depending on plan | Good alternative, but less feature-rich |
Holafly | Heavy data users who want unlimited data | Unlimited-focused | No comparable built-in Nord Security bundle | Often limited depending on plan | Usually data-only for travel eSIMs | Better for unlimited data, usually less flexible on price |
Saily vs Airalo: Fixed-data pricing is close, but Saily gives you more than just mobile data. In my Switzerland tests, Saily connected to Salt and Sunrise depending on location, and the app also includes built-in web protection, ad blocking, virtual location features and an optional US phone number add-on. That makes Saily the stronger overall travel eSIM for most visitors.
Holafly vs Saily: Holafly is attractive if you want unlimited data and do not want to think about usage. For a normal 1–2 week Switzerland trip, I still prefer Saily because the fixed-data plans are cheaper for most travellers, hotspot is supported, top-ups are simple, code TECH gives 15% off, and Saily also offers an optional US phone number add-on inside the app.
Who Should Use Saily in Switzerland
Saily is a good fit if you:
Want a single eSIM that switches networks automatically as you move around the country
Are visiting for a standard 1–2 week trip with normal data needs (maps, messaging, some streaming, occasional hotspot use)
Plan to continue on to other European countries afterward — one Saily eSIM covers 35+ European destinations. If Switzerland is part of a wider Europe trip, also see my real Saily Portugal test and my broader Saily Europe review.
Want built-in web protection, ad blocking, virtual location features, easy top-ups and optional US phone number functionality in one travel app
Saily may not be the best fit if you:
Need genuinely unlimited data with zero tracking — Holafly's unlimited plans remove that mental overhead, at a higher price
Need the absolute lowest entry price for a tiny 1 GB top-up — Airalo is sometimes a cent or two cheaper on the smallest plans
Need a real Swiss +41 phone number for local calls, Swiss banking setup or Swiss SMS verification — Saily offers an optional US phone number add-on, but not a local Swiss number
Final Verdict
After testing Saily on Salt 5G in St. Gallen (271–370 Mbps), on Salt LTE at Lake Constance in Rorschach (140 Mbps, 0% packet loss), and on Sunrise LTE/5G during a hike in the Alpstein at 1,500 m (34–65 Mbps), my conclusion is straightforward: for most travelers visiting Switzerland, Saily is the eSIM I'd recommend first. Setup takes under 5 minutes, the connection held up everywhere I tested it — from city centres to Alpine terrain — and it costs a fraction of US carrier roaming.

What is the Saily discount code for Switzerland?
My recommended Saily discount code for Switzerland is TECH. It gives 15% off Saily plans, including Switzerland eSIMs and Saily Ultra.
Does Saily give you a phone number in Switzerland?
Saily's Switzerland eSIM data plans are primarily for mobile data, but Saily now also offers an optional US phone number add-on inside the app. This gives you a persistent +1 number for calls, texts, OTPs and app sign-ups. It is not a Swiss phone number, so it is not the same as getting a local Swiss SIM card with a +41 number.
For most Switzerland travellers, this is still useful: you can use Saily for mobile data, keep your regular number active if needed, and optionally add a Saily US phone number for travel communication or verification use cases.
Can I top up my Saily Switzerland eSIM?
Yes. You can add more data directly in the Saily app if you run out during your trip. This is much easier than buying a local Swiss prepaid SIM, especially for short stays where ID registration and store visits are not worth the hassle.
Is Saily eSIM better than Airalo for Switzerland?
For most travelers, in my experience, yes. Pricing is comparable, but Saily connected to multiple Swiss networks in my tests, and its app includes built-in web protection. See the full Saily vs Airalo comparison.
Does Saily work in the Swiss Alps?
In my tests, yes. I had reliable signal during a hike in the Alpstein at 1,500 m and have personally had reliable signal on the Jungfraujoch at 3,454 m. Switzerland's mobile infrastructure is excellent even at altitude, which benefits any eSIM running on it.
Can I buy a Saily eSIM on arrival in Switzerland?
No — Saily is purchased online before you travel. Local Swiss prepaid options can require ID registration in a store and may be less convenient for short trips. For most international travelers, installing a Saily eSIM before arrival is simpler than sorting out a local option after landing.
Does Saily eSIM support hotspot in Switzerland?
Yes. I used it to connect a laptop via hotspot during my test with stable, fast speeds.
Does Saily work during Alpine hiking in Switzerland?
Yes, in my tests. I tested Saily in the Alpstein at Bogartenlücke on 31.05.2026 and near Schwägalp / Säntis-Talstation on 05.06.2026, both on Sunrise via iPhone 15 Pro, approx. 1,500 m. LTE delivered 34–44 Mbps at Bogartenlücke and 42–130 Mbps near Schwägalp — sufficient for navigation, WhatsApp, and maps throughout. 5G peaked at 65.25 Mbps once stable. One brief signal dropout at the start of the Bogartenlücke ascent, typical for Alpine terrain.
