Key takeaways
Switzerland has some of the best mobile coverage in Europe, with Swisscom winning national benchmarks for three consecutive years and near-universal 5G reach. A Roamix Switzerland eSIM activates on arrival, works on mountain railways and in most Alpine resort towns, and avoids the steep cost of carrier roaming in one of the world's most expensive countries. Plan 5 to 10 GB for a week.
- Swisscom wins independent national benchmarks every year and offers the best high-altitude Alpine coverage.
- A Roamix eSIM activates on arrival at Zurich or Geneva airport, avoiding airport SIM queues.
- Switzerland is expensive, and carrier roaming here can cost significantly more than elsewhere in Europe.
- Many nationalities visit visa free under the Schengen Agreement, but check current ETIAS requirements.
- Budget 5 to 10 GB for a week, adding more if you plan to stream or work remotely from a chalet.
Best way to get data in Switzerland
A Roamix eSIM is the clearest way to get local Swiss network speeds without the steep roaming costs that hit non-EU visitors in particular.
| Option | Best for | Good to know |
|---|---|---|
| Roamix eSIMRecommended | Best for: Most travellers | Instant activation on a premium Swiss network, works on mountain railways and in most resort villages, nothing physical to collect. |
| Local physical SIM | Best for: Long stays needing a local number | Available at the airport and in carrier stores but requires passport ID and swapping your home SIM. |
| Pocket wifi | Best for: Groups sharing one connection | Another device to charge, return and pay a deposit on, with the same coverage as a local SIM. |
| Carrier roaming | Best for: Very short trips with no setup time | The most expensive option, especially for non-EU visitors. Switzerland is outside the EU so EU roaming protections often do not apply. |
Free wifi is available in hotels, train stations and many cafes, but speeds vary and public networks are not secure for banking. Mobile data is far more practical for navigation and payments on the move.

Download offline timetables and maps for any Alpine hiking area before you leave the city, so you stay oriented above the signal line without burning data.
How to set up a Switzerland eSIM
A Roamix Switzerland eSIM is best installed over wifi before departure. It activates automatically when you connect to a Swiss network on arrival, so you are online before the airport train departs.
- 1
Buy your plan on the Roamix Switzerland eSIM page before you travel.
- 2
Install the eSIM over wifi by scanning the QR code in your activation email.
- 3
Label it Roamix and keep your home SIM as the primary for calls and SMS.
- 4
Enable data roaming for the Roamix line only.
- 5
Land in Switzerland and the eSIM connects automatically to a local network.
Works on eSIM capable phones including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S and Z models. The phone must be carrier unlocked.
The correct APN is configured automatically on most devices. If data does not start, apply the APN from your order and toggle airplane mode off and on.
No data on arrival usually means data roaming is off for the Roamix line or the network needs manual selection. Restart the phone after checking both settings.
Visa and entry for Switzerland
Switzerland is a Schengen member, so EU and EEA citizens enter freely. Visitors from many other countries are also visa free for stays of up to 90 days in any 180 day period under the Schengen Agreement. Note that Switzerland uses the Swiss franc, not the euro, despite being in the Schengen zone.
- eVisa or ETA
- An ETIAS travel authorisation is expected for most visa-free non-EU visitors entering Schengen. Check the official ETIAS website for current launch status and whether your nationality is affected.
- Passport validity
- Your passport must be valid for at least three months beyond your planned Schengen departure and issued within the last ten years.
- Onward ticket
- Proof of onward travel and evidence of sufficient funds for your stay may be requested at the border.
Keep digital copies of travel documents and booking confirmations accessible on your phone. Your Roamix eSIM keeps everything accessible offline and online throughout your trip.
Entry requirements change. Always confirm current rules with official Swiss immigration sources or your nearest embassy before booking.
When you land in Switzerland
0 of 5 done
How people message here
WhatsApp is the dominant messaging app in Switzerland across all language regions. SMS and iMessage are also common, and Swiss Germans sometimes use Threema for privacy reasons.
Do you need a local number?
You rarely need a local Swiss number as a tourist. A Roamix data line covers WhatsApp calling and messaging to hotels, guides and local contacts.
Keep your home SIM active for SMS two-factor codes while using the Roamix eSIM for data. Switzerland has excellent indoor coverage in most hotels.
Airports in Switzerland
ZRH
Zurich Airport
Zurich
Free WiFi throughout the terminal. Zurich Airport's WiFi is well-managed and relatively uncongested compared to larger European hubs.
Zurich Airport has a direct underground train station (Zurich Flughafen) beneath the terminal. The SBB train to Zurich Hauptbahnhof takes 10 minutes and runs every 10 minutes. Install your Roamix eSIM before boarding at your origin airport to arrive with Swisscom 5G already active for the SBB app and Google Maps.
GVA
Geneva International Airport
Geneva
Free WiFi available throughout the terminal. Geneva Airport is compact and easy to navigate.
Geneva Airport is one of the only airports in the world where you can take a free train to the city centre. The Geneva Cornavin mainline train station connects via a direct underground walkway. With Roamix data active, you can plan your onward connection to Lausanne, Zermatt, or Interlaken the moment you land.
BSL
EuroAirport Basel-Mulhouse-Freiburg
Basel
Free WiFi available. The airport straddles the French-Swiss border with separate terminals for each country. Check you exit via the correct (Swiss) exit for SBB train connections.
The SBB train from the Swiss exit of EuroAirport connects to Basel SBB station in 14 minutes. Basel is the gateway to Bern, Zurich, and Lucerne by fast SBB intercity train. Roamix data is useful for navigating the dual-country terminal and loading the SBB timetable.
BRN
Bern Airport
Bern
Free WiFi available. Bern Airport is a small regional airport serving limited European routes, primarily used by domestic and regional travellers.

Getting around Switzerland
Switzerland's transport system is one of the most precise and integrated on earth. SBB trains, PostBuses, mountain railways and lake steamers connect almost everywhere, and a connected phone keeps timetables, ticketing and live updates running smoothly.
SBB trains and intercity rail
The backbone of Swiss travel. The SBB app needs a live connection for real-time timetables and mobile ticketing on most routes.
Mountain railways and cable cars
Trains like the Glacier Express and Jungfraujoch rack railway typically have 4G coverage below the treeline, with signal often improving at top stations where masts are installed.
PostBus
Yellow PostBuses reach remote valleys where trains do not run. 4G is available on most routes but can drop in the deepest gorges.
Rideshare and taxis
Uber operates in Zurich and Geneva. Local taxi apps and street taxis are available in all cities and resort towns and need a live connection to book.
The Swiss Travel Pass gives unlimited train, bus and boat travel plus free museum entry. Book it before arrival and load it on the SBB app on your connected phone.
Money and payments in Switzerland
Switzerland uses the Swiss franc, not the euro. Cards and contactless are widely accepted, but carry a small amount of CHF for mountain huts, rural markets and small village restaurants that may not accept cards.
- Cards and cash
- Major hotels, restaurants and shops accept cards and contactless. Smaller Alpine restaurants, cable car stations and farm shops often prefer cash.
- ATMs
- ATMs are widely available in cities and resort villages. Always choose to be charged in CHF rather than your home currency to avoid poor dynamic conversion rates.
- Payment apps
- Apple Pay and Google Pay are widely accepted in Swiss cities. Twint is the dominant Swiss mobile payment app used by locals at markets and small shops.
- Tipping
- Tipping is not obligatory but rounding up or adding five to ten percent is appreciated for good service in restaurants and taxis.
Daily budget
Budget travellers spend around 100 to 150 CHF per day, mid range 200 to 350 CHF. Switzerland is consistently one of the most expensive countries in the world.
Local tips for Switzerland
- Language
- Switzerland has four official languages: German in the north and centre, French in the west, Italian in the south, and Romansh in parts of Graubunden. English is widely spoken in tourist areas and cities. A translation app helps with menus in rural French and Italian areas.
- Food
- Cheese fondue and raclette are genuinely eaten at home, not just for tourists. Look for rosti in the German-speaking regions, malakoff fritters near Lake Geneva and pizzoccheri pasta in the Italian-speaking Ticino. Book mountain restaurant tables in advance in peak ski season.
- Plugs
- 230V, Type J plug
Apps worth having
SBB Mobile
transit
Official Swiss rail app for buying tickets, checking live timetables across trains, PostBuses and lake boats.
Meteo Swiss
weather
The official Swiss weather service with reliable mountain and valley forecasts essential for hiking and skiing safety.
Twint
payments
The dominant Swiss mobile payment app, widely used at markets, cafes and small shops across all language regions.
Safety and health in Switzerland
Switzerland is one of the safest countries in the world for travellers. The main risks are mountain related, including weather changes, altitude and avalanche in winter. Staying connected is important for receiving mountain alerts.
- Stay reachable
- Keep your Roamix eSIM active to check the official Meteo Swiss app for sudden weather changes on Alpine routes and to call the mountain rescue service on 1414 if needed.
- Health
- Healthcare is excellent but extremely expensive without insurance. Ensure you have comprehensive travel insurance covering mountain rescue, which can cost thousands of CHF without it.
- Tap water
- Tap water and mountain spring water are safe to drink and of extremely high quality throughout Switzerland.
Networks and coverage in Switzerland
Switzerland has one of the most advanced mobile networks in Europe, built to handle the country's unique geography of dense cities, steep valleys and high-altitude ski resorts. Swisscom has won the nPerf national benchmark award for three consecutive years and covers 99% of the population with 5G. A Roamix Switzerland eSIM connects you to a premium local network on arrival, delivering fast data on mountain railways, in lakeside towns and across the cities.
Swisscom
The clear benchmark leader with the highest download speeds, best streaming scores and the strongest signal in remote valleys and ski villages.
Sunrise
Excellent urban performance and the fastest 5G download speed in some city tests, with good coverage in main tourist destinations.
Salt
Fully competitive in cities and on main roads, with the best latency scores of the three operators, making it strong for real time apps.
- Typical speeds
- Urban 5G typically delivers 100 to 270 Mbps. Swisscom leads on download speed with a median of 174 Mbps nationally.
- 5G
- All three operators have live 5G above 93% population coverage, with Swisscom reaching 99% by the end of 2025.
Swisscom has the deepest valley and altitude coverage of the three operators and is the most reliable choice for trips involving off-piste skiing or high-altitude hikes.
Coverage is outstanding by any standard, but deep Alpine valleys, high trails above 2,500 metres and some narrow gorges can still show dead zones. Download offline maps before hiking or skiing in remote areas. Swiss networks use common LTE and 5G bands, so a Roamix eSIM works on virtually any recent unlocked phone with no band incompatibility.
Where to go in Switzerland
Switzerland packages extraordinary variety into a small country. Glacier lakes, cheese-farm valleys, medieval towns and world class ski resorts sit within hours of each other, and the rail network is legendary for its precision. A Roamix eSIM keeps navigation, SBB booking apps and translation running everywhere from Zurich's trams to the Glacier Express.
Best time to visit
December to March for skiing, June to September for hiking and lake swimming. Spring wildflower meadows from April to May and autumn foliage in October are quieter and stunning.
Zurich and German-Speaking Switzerland

Swisscom 5G throughout Zermatt village. Coverage extends to Riffelberg at 2,582 metres and Klein Matterhorn at 3,883 metres (highest cable car in the Alps). Remote glacier hikes beyond lift stations have variable coverage.
Ticino and Italian-Speaking Switzerland
South of the Alps, Ticino has a completely Mediterranean character: palm trees on Lake Lugano and Lake Maggiore, piazza culture in Lugano's old town, and hiking trails through chestnut forests. Lugano, Locarno, and Ascona form a triangle of Italian-accented Swiss life.
- Lugano Old Town piazzas
- Monte San Salvatore
- Locarno Film Festival venue
- Verzasca Valley bungee jump
- Bellinzona UNESCO castles
Swisscom 5G in Lugano city centre and along the lakefront. Locarno and Bellinzona fully covered. The Monte San Salvatore funicular area in Lugano is covered. Remote valley routes toward the St. Gotthard Pass are 4G.
Off the beaten path
An impossibly turquoise river running through a steep Ticinese granite canyon, with natural swimming pools, a Roman-arch double bridge at Lavertezzo, and the Verzasca Dam where James Bond's bungee jump in GoldenEye was filmed.
Signal: Swisscom 4G in Locarno and Tenero at the valley entrance. Signal is intermittent through the canyon sections. Lavertezzo, the most visited village, has basic coverage.
Switzerland's smallest canton by population and the last to grant women the right to vote (in 1990). Ornate painted house facades, Landsgemeinde open-air democracy, and Appenzeller Sennenhunde dogs on every street. The Ebenalp ridge walk is one of Switzerland's best day hikes.
Signal: Full Swisscom 5G in Appenzell town centre. Ebenalp mountain area and the Wildkirchli cave chapel are covered. Remote Seealpsee lake trails thin out.
A perfectly preserved medieval hilltop village above the Sarine Valley, with Gruyere cheese dairies, the H.R. Giger Museum (the Alien artist), and a 13th-century castle. One of the most photogenic villages in Switzerland.
Signal: Full Swisscom coverage in Gruyeres village and at the castle. The surrounding farmland and Alpine pastures have good 4G.
Seventy-two waterfalls cascade from vertical cliffs in a glacial valley that inspired Tolkien's Rivendell. The Trummelbach Falls inside the mountain are the only glacially-fed waterfall in Europe accessible by tunnel lift.
Signal: Swisscom 4G throughout Lauterbrunnen town and along the valley floor. Murren above the valley on the cliff is 4G. Wengen on the east side is 4G. Waterfall viewpoints at Staubbachfall and Trummelbach are covered.
The Engadine is the highest permanently inhabited valley in the Alps, home to St. Moritz (twice Olympic host), the Bernina Express panoramic railway, and one of Switzerland's wildest national parks. Romansh culture survives in villages like Scuol and Sent.
Signal: Swisscom 5G in St. Moritz village and Pontresina. The Bernina Pass road has 4G along most of its length. Remote Val Forno and Roseg Valley glacier trails are weak.
A perfectly intact medieval walled town on the shore of the Murtensee, where the famous torch-lit 17 km New Year's Eve race (the Murtenlauf) takes place. Barely touched by mass tourism, 30 minutes from Bern by train.
Signal: Full Swisscom coverage throughout Murten's old town, the medieval walls, and the lakefront.
The longest glacier in the Alps at 23 km, a UNESCO World Heritage Site, and one of the most dramatic natural spectacles in Europe. Accessible from Moosfluh cable car above Riederalp or the Bettmerhorn above Bettmeralp.
Signal: Swisscom 4G at the Jungfraujoch viewpoint and Bettmerhorn cable car station. The glacier moraine trails are intermittent. Riederalp and Bettmeralp villages at the top of the cable cars have coverage.
Zurich's former industrial district, now home to the Puls 5 industrial hall, the Schauspielhaus Schiffbau theatre, Im Viadukt market under the railway arches, and the densest bar and restaurant scene in the city. Far more interesting than the tourist Bahnhofstrasse for an evening.
Signal: Dense Swisscom 5G throughout Zurich-West, the Langstrasse, and the IMM and Schiffbau venues.
The most powerful waterfall in Europe by volume, a thunderous curtain of water 150 metres wide and 23 metres high on the Rhine. Viewable by boat from the centre rock in summer, with a dramatic closeness that photographs cannot fully convey.
Signal: Full Swisscom 5G throughout the Rhine Falls site, the boat jetties, and the Laufen Castle viewpoint.
Pontresina is the quieter, more authentic alternative to St. Moritz, 10 minutes away by RhB train. The Morteratsch Glacier trail is one of the best free glacier walks in Switzerland, with historical markers showing the ice retreat since 1878.
Signal: Swisscom 4G in Pontresina village and at the Morteratsch glacier car park and trail start. The upper glacier moraine trail thins out above the information markers.
Events and seasons in Switzerland

August, 11 days
Locarno International Film Festival
Locarno, Ticino
One of the world's oldest and most prestigious film festivals, held since 1946. The Piazza Grande outdoor screening for 8,000 people under the stars is one of European cinema's greatest experiences. The Pardo d'Oro (Golden Leopard) is presented to the best international film.
Through the year
- Spring
- April and May see snow melting into meadows, with Zurich's Sechselauten in April and the first Alpine wildflowers in May.
- Summer
- June to August is ideal for hiking, lake swimming and outdoor festivals. Alpine wildflowers peak in late June and July, and the Montreux Jazz Festival draws huge crowds.
- Fall
- September to November brings golden light on the vineyards, fewer crowds and the grape harvest season in the Lavaux terraces above Lake Geneva.
- Winter
- December to March transforms Switzerland into the world's premier ski destination, with Zermatt, Verbier, St. Moritz and Davos all fully operational.
Working remotely from Switzerland
Switzerland is an excellent remote work base with superb internet, abundant coworking in Zurich and Geneva, and stunning surroundings, though the cost of living is the highest in Europe.
- Connection
- Urban 5G and resort hotel fixed internet both handle video calls and cloud uploads easily. A Roamix plan of 20 GB or more covers a working week alongside daily exploring.
Most Swiss coworking spaces require a registered account and advance booking. Use your connected phone to reserve a desk before arriving in the city.
