SIM Cards in Switzerland — Complete Expat Guide 2026

Switzerland has three main physical mobile networks. Swisscom has the best overall coverage including remote mountain areas and is the most reliable network in the country. Sunrise has strong urban and suburban coverage and competitive pricing. Salt is the most budget-friendly of the three with good coverage in cities and towns.

Almost all cheaper brands and MVNOs run on one of these three networks so choosing a budget provider does not always mean worse coverage — it depends which network they use.

Important: Switzerland is not part of the EU which means EU free roaming does not apply. This catches out almost every new arrival from an EU or EEA country — your existing European SIM will charge international rates from the moment you land.

Prepaid SIM cards require no contract, no credit check and no Swiss address. You can buy one at Zurich airport before you clear customs. They are the right choice for the first 4 to 8 weeks while you are completing Anmeldung, waiting for your permit and finding permanent housing. The downside is higher cost per GB compared to postpaid plans.

Postpaid contracts offer lower monthly costs, more data, and often include EU roaming. They require a Swiss registered address, a valid residence permit and sometimes a credit check. You cannot set one up until your Anmeldung is complete and you have a permit in hand.

Lycamobile Switzerland — runs on the Swisscom network, available at Migros, Coop, airport kiosks and online. Popular with new arrivals because of low international calling rates and wide availability. Best for: first week of arrival and anyone making frequent international calls back home.

Swisscom prepaid — most expensive prepaid option but best coverage anywhere in Switzerland including mountains and rural areas. Available at Swisscom shops, Migros and online. Best for: anyone arriving in a rural canton or planning mountain hikes immediately.

Salt prepaid — affordable data packages on the Salt network, available at Salt shops and online. Best for: urban residents in Zurich, Geneva or Basel who want a simple low-cost option.

Yallo prepaid — budget-friendly, runs on Sunrise network, managed entirely online and via app. Best for: data-heavy users who are comfortable with a digital-only provider.

Aldi Mobile and Lidl Connect — available directly in Aldi and Lidl stores, very low cost, runs on Sunrise network. Best for: absolute lowest cost option for light users.

M-Budget Mobile prepaid — Migros own brand, runs on Swisscom network, available at any Migros store. Best for: anyone who wants Swisscom network coverage at a much lower price than Swisscom directly.

Swisscom postpaid — premium pricing, the best and most consistent network in Switzerland, English-language customer support available in major cities. Worth the extra cost for frequent travellers and anyone living or working outside major urban centres. Best for: high earners, families, frequent mountain travellers, anyone who cannot afford patchy coverage.

Sunrise postpaid — strong urban coverage, competitive monthly prices, good international roaming add-ons for EU travel. The best balance of price and quality for most city-based expats. Best for: most expats living in Zurich, Geneva, Basel or Bern.

Salt postpaid — the most affordable postpaid plans of the three main networks, decent urban coverage. Best for: budget-conscious expats who live and work in cities and rarely travel to remote areas.

Wingo — Swisscom subsidiary offering Swisscom network quality at significantly lower prices than Swisscom directly. Managed online. Best for: expats who want reliable Swisscom coverage without the Swisscom price tag. One of the best value options in 2026.

Yallo postpaid — digital-first provider running on Sunrise network, very competitive pricing, app-based account management. Best for: tech-comfortable expats who want the cheapest postpaid plan on a solid network.

M-Budget Mobile postpaid — Migros brand, Swisscom network, very affordable. Best for: families or anyone wanting Swisscom coverage at a budget price.

At the airport: Swisscom and Lycamobile kiosks are available at Zurich Airport before baggage claim. Sunrise is available in the arrivals hall. These are the most convenient options on arrival day — prices are the same as buying in the city.

At Migros and Coop supermarkets: Lycamobile, M-Budget Mobile, Swisscom prepaid and Salt prepaid are all available at most large Migros and Coop stores. These are starter packs with a physical SIM and a QR code for setup. Available across all 26 cantons.

At Aldi and Lidl: Aldi Mobile and Lidl Connect starter packs are available at checkout counters in most stores.

At network stores: Swisscom, Sunrise and Salt all have branded shops in city centres and major shopping centres. Staff can help with setup, eSIM configuration and switching from prepaid to postpaid.

Online: all providers allow online ordering with delivery to a Swiss address. Most also support eSIM activation online without needing a physical SIM. Requires a Swiss address for delivery — order once your Anmeldung is complete.

At the post office: Swisscom SIM cards and top-up credit are available at most Swiss Post offices, which are found in every town and commune across all 26 cantons.

All three main networks and most MVNOs now support eSIM. If your phone supports eSIM (most phones released after 2020 do), this is the most convenient option — no waiting for a physical card, activate instantly via QR code. Particularly useful on arrival day before you have a Swiss address. Swisscom, Sunrise, Salt, Wingo and Yallo all support eSIM activation.

To check if your phone is eSIM compatible, go to Settings → Mobile / Cellular → Add eSIM (iPhone) or Settings → Connections → SIM manager (Android). Activation typically involves scanning a QR code provided by the carrier and following on-screen prompts — the whole process takes under five minutes.

Since 2023 all Swiss SIM cards — prepaid and postpaid — require identity verification. You will need to provide a valid passport or ID card during purchase or activation. For online and app-based registration this is typically done via a short video verification or ID photo upload. For in-store purchases the retailer records your ID details. This is a legal requirement under Swiss telecommunications law and applies to all providers without exception.

Switzerland has bilateral agreements with EU and EEA countries but roaming is not free as it is within the EU. Most postpaid plans offer optional EU roaming add-ons at CHF 5 to 15 per day or as a monthly add-on. Prepaid roaming rates are significantly higher.

If you travel frequently to EU countries for work or to visit family, factor in roaming costs when choosing a plan — Sunrise and Swisscom postpaid plans generally have the most competitive roaming add-ons. For calls back to your home country, Lycamobile and Yallo typically offer the best international calling rates.

• Arriving this week and need a number immediately: buy a Lycamobile or M-Budget Mobile prepaid SIM at the airport or a Migros on your first day.
• Staying long term and want the best coverage everywhere including mountains: get Swisscom prepaid to start, then switch to Wingo postpaid once your permit and address are registered — Swisscom network at a much lower price.
• Based in Zurich, Geneva or Basel and want the best value postpaid plan: Sunrise or Yallo postpaid are the best balance of price and quality for city-based expats.
• Want the absolute cheapest option and live in a city: Yallo or Salt postpaid for the lowest monthly cost, or Aldi Mobile prepaid for occasional use.
• Travel frequently to EU countries for work: Swisscom or Sunrise postpaid with an EU roaming add-on. The monthly add-on is significantly cheaper than day-rate roaming charges.
• Have a family and want to keep costs down: M-Budget Mobile family plans on Swisscom network offer the best combination of coverage and affordability for multiple lines.
• Work remotely and need reliable data everywhere: Swisscom postpaid. Do not compromise on network quality if your income depends on connectivity.
