eSIM in Switzerland

1. What is an eSIM and which phones support it?

An eSIM (embedded SIM) is a digital SIM card built directly into your device. Instead of inserting a physical SIM card, you activate a mobile plan by scanning a QR code or entering an activation code provided by your carrier. The profile is downloaded over the internet and stored in the phone's hardware.

Key differences from a physical SIM

• No physical card: nothing to swap out or lose.
• Multiple profiles: many devices can store several eSIM profiles and switch between them (though typically only one is active at a time, unless your device supports dual active eSIM).
• Instant activation: you can activate a plan minutes after purchase, without waiting for a delivery.

Device compatibility

eSIM support has become widespread, but compatibility still varies by device and carrier. As a general guide:

• iPhone: supported from iPhone XS (2018) onwards. iPhone 14 and later (US models) are eSIM-only with no physical SIM tray.
• Android: many flagship and mid-range Android phones support eSIM, including models from Samsung, Google Pixel, and others. Check your specific model's specifications.
• Important: some phones are carrier-locked and may not support eSIM with other carriers. Check with your device manufacturer or carrier before buying an eSIM plan.

2. Before you arrive: travel eSIM options

A travel eSIM lets you buy and activate data connectivity before you even board your flight — meaning you land in Switzerland with internet access ready to go. Several international providers sell travel eSIMs that cover Switzerland.

Why you may need a separate plan for Switzerland

Switzerland is not a member of the European Union. This means EU roaming regulations do not apply. If you currently have a European mobile plan with "roam like at home" EU coverage, Switzerland is almost certainly not included. Check your existing plan's Switzerland roaming rates explicitly — they can be very high.

What travel eSIMs typically offer

• Data only: most travel eSIMs provide a data-only connection. You will not have a Swiss phone number for calls or SMS.
• Prepaid data packages: you purchase a set amount of data (e.g. 3 GB, 10 GB) for a set period.
• Multiple country coverage: many travel eSIM plans cover a region or multiple countries, making them useful if you'll be travelling through several countries before arriving.

Pros and cons of travel eSIMs

For arrivals, a travel eSIM is an excellent bridge for the first few days while you sort out a local plan. Compare options from international eSIM providers — check their coverage maps to confirm Switzerland is included before purchasing.

3. After arrival: Swiss eSIM and prepaid options

Once you're in Switzerland, you have a range of options from the three main Swiss networks and their MVNOs (mobile virtual network operators).

Swiss prepaid SIM / eSIM

The quickest way to get a Swiss number. Prepaid SIMs and eSIMs require no contract, no bank account, and are available at:

• Railway station shops (SBB/CFF Travelshop) — available at major stations across Switzerland
• Provider stores (Swisscom, Sunrise, Salt)
• Large supermarkets (Migros, Coop) and electronics stores
• Online, with activation by post or digitally

Note: Swiss law requires identity verification for SIM registration. You will need a valid photo ID (passport or national ID card).

Swiss prepaid plans from main providers

• Swisscom (Natel Easy prepaid): Swisscom has the widest network coverage in Switzerland. Their prepaid range includes data and call bundles. Check current pricing directly on swisscom.ch.
• Sunrise: Switzerland's second-largest operator, merged with UPC. Prepaid options available via sunrise.ch.
• Salt: solid coverage in urban areas and along main transport routes. Prepaid options at salt.ch.

Prices and data bundles change regularly. Always check the provider's current website for up-to-date plans before purchasing.

Post-paid subscriptions

Once you have a Swiss address and ideally a Swiss bank account, a post-paid monthly subscription typically offers better value per GB than prepaid. See our dedicated Mobile Plans guide for a full comparison.

5. Dual SIM setup

Many modern smartphones support two active connections simultaneously — one physical SIM and one eSIM, or (on some newer devices) two eSIMs. This is particularly useful for expats and cross-border workers.

Common dual SIM use cases

• Keep your home country number: retain a foreign SIM for calls and messages from family, while using a Swiss number for local use.
• Cross-border workers: a Swiss number for work, a home-country SIM for personal use and EU-side calls.
• Travel eSIM + Swiss number: use a travel eSIM for data on arrival while retaining your existing SIM for calls.

How to set up dual SIM

On most iPhones (iOS 13+), go to Settings → Mobile Data → Add Mobile Plan to add an eSIM. On Android, the process varies by manufacturer — look under Settings → Connections or Settings → Network & Internet. Your device manual or manufacturer support website will have device-specific instructions.

6. Network coverage in Switzerland

Switzerland has three national mobile network operators. MVNOs (mobile virtual network operators) run their services on top of these networks:

Checking coverage before you choose

Coverage maps can look similar at a national level, but differences emerge in valleys, mountain areas, and tunnels. Before committing to a provider:

• Use each provider's coverage map on their official website to check your home address and workplace.
• Check coverage along your regular commute route.
• BAKOM (Federal Office of Communications) publishes independent coverage data at bakom.admin.ch.

If you live or work in a rural or Alpine area, Swisscom typically has the strongest coverage. For urban areas, all three main networks perform well.
