Switzerland

Staying connected in Switzerland

Switzerland is often the middle leg of a France – Switzerland – Italy tour, but more travellers now give it a full week: Lucerne with Rigi and Pilatus, Interlaken as the gateway to the Jungfraujoch, Zermatt beneath the Matterhorn, and Zurich and Geneva for business. Scenic rail journeys such as the Glacier Express and Bernina Express anchor many itineraries.

Summer (June to September) is for hiking and lakes; winter (December to March) brings skiing in Zermatt, St. Moritz and Verbier. You will need data most when catching tight train connections, checking summit weather and webcams before buying mountain tickets, and following hiking trails.

Coverage and networks

The plan information names these networks in Switzerland: Sunrise and Salt.

Travelling on to France or Italy? Multi-country Europe plans can work, but confirm Switzerland appears in the plan's country list — not every Europe plan includes it.

Signal and speed depend on where you are, your device and network conditions, and can differ between plans.

Choosing a data allowance

eSIM plans for Switzerland currently last 1 to 30 days and come in these types:

• Daily data (500MB, 1GB, 2GB and 3GB per day): suits a steady routine. Check when the daily allowance resets and what happens once it is used.
• Total data (3GB to 50GB): one allowance for the whole trip, handy when some days are heavier than others.
• Unlimited: always read the fair-use policy; after a set amount, speed may be reduced.

Suggestions for this trip

• A 5–7 day rail loop through Lucerne, Interlaken and Zermatt: 1GB per day covers train apps, maps and photos; if you plan to share mountain videos regularly, choose 2GB per day.
• A 7–10 day ski trip with little use on the slopes but video calls in the evening: 1GB or 2GB per day is sensible; for 15–20 days, a 10GB or 20GB total data plan can work better.
• A short business trip to Zurich or Geneva: a 3GB or 5GB total data plan; for back-to-back video meetings, look at the unlimited option (fair-use policy).

Count your arrival and departure days. Before paying, check the exact plan for when validity starts, how days are counted, and whether hotspot, calls or SMS are included; these differ between plans.

Before you go

• Trains: SBB Mobile is the go-to app for timetables, tickets and platforms; trains, buses, lake boats and many mountain railways share one ticketing system.
• Travel passes: If you use a Swiss Travel Pass or discount card, keep the digital version on your phone and an offline copy in case you are asked to show it.
• Currency: Switzerland uses the Swiss franc (CHF), not the euro; some places accept euros but give change in francs. Contactless cards are accepted almost everywhere.
• In the mountains: Weather turns quickly, so check forecasts and summit webcams before heading up, and download offline trail maps so tunnels and deep valleys do not leave you stuck.
• Local SIM: Passport registration is required. The emergency number is 112, and mountain air rescue has its own number, 1414.
• eSIM setup: Before buying, make sure your phone supports eSIM and is not carrier-locked. Install the eSIM before you fly, on a stable Wi-Fi connection, following the instructions sent with your plan.
• On arrival: Set the travel eSIM as your mobile data line and follow its roaming instructions. Turn off data roaming on your home SIM to avoid unexpected charges.
