In short
If the phone is unlocked and takes an eSIM profile, buy a Switzerland eSIM plan: install at home, no queue, nothing to return. A local plastic SIM still helps for a +41 number, a long stay at a low franc-per-GB price, or a handset that refuses eSIM. eSIM plans sit on the Switzerland comparison. Swisscom, Sunrise and Salt shops take francs, passport in hand.
- Compatible phone, city break or classic circuit. eSIM. Check the model in the compatibility tool.
- Need to call a hotel or a guide on a local number. Official prepaid (often Swisscom Prepaid Flat). Travel eSIMs are often data only.
- Three weeks, heavy volume, tight budget. Compare the counter price per GB with the eSIM table before you queue.
- Late flight into ZRH or GVA, shop shut. eSIM already on. Do not count on the kiosk.
At Zurich Airport the Swisscom shop is not open for every night landing. The eSIM is already on the phone if you scanned it on home Wi-Fi. Both ride the same kind of Swiss mast. Take the eSIM as soon as the handset accepts it, unless you truly need a Swiss number or a three-week local tariff.
Switzerland travel eSIM vs a plastic SIM if the phone is compatible
Unlocked phone that takes an eSIM: buy a Switzerland plan. Maps, SBB Mobile, Twint, translation. No deposit, no nano-SIM swap in a sleeve, no queue at the station on arrival day.
Install the profile before the flight, on stable Wi-Fi. Turn data roaming on the eSIM only. Keep the UK line on for bank texts.
Airalo and Holafly cover Switzerland: open the plan page (network, 5G, hotspot) before you pay, not the brand homepage. Off the plateau, look for Swisscom on the operator line. Radio detail lives in best mobile networks in Switzerland.

When to buy a Swisscom, Sunrise or Salt local SIM
The plastic SIM wins in four cases.
- You want a +41 number to call a hotel, a guide or a restaurant without WhatsApp.
- The handset is carrier-locked, or the compatibility tool says no.
- The stay is long and the prepaid price per GB, checked on the day, clearly beats the eSIM pack.
- You prefer a shop counter, passport scanned, top-ups in francs.
Even at 15 days, if every pocket has a recent iPhone and WhatsApp is enough: one eSIM per adult, not a nano-SIM “just in case”.
Swisscom, Sunrise and Salt also sell local eSIM (Prepaid Flat, in-store prepaid). The gesture looks like plastic: ID, sometimes a My Swisscom account. It is not the Airalo QR you scan at home. Swisscom Prepaid Flat 7 can sometimes be ordered online, but activation can ask for a Swiss number for 2FA: plan on the shop if that blocks.
Where to buy a Switzerland SIM (airport, station and city)
Official shops for all three operators sit at Zurich (ZRH) and Geneva (GVA) arrivals, often Zurich HB, Bern and Lausanne too, with shorter hours than the airport. Passport. Skip the unsigned seller in the hall.
| Channel | What you buy | ID | What to know |
|---|---|---|---|
| Airport shop Swisscom / Sunrise / Salt | Tourist prepaid, sometimes local eSIM | Passport | Price often a bit higher than in town. ZRH stays open late more often than GVA. |
| Station or city shop, Swiss Post (Swisscom) | Same operators, sometimes a cheaper kit | Passport | Useful if the flight lands and the stand is shut, provided you already have an eSIM for SBB. |
| Travel eSIM (catalogue) | Data, sometimes hotspot | Card at home | No Swiss number. Operator column on the comparison. |
Prepaid bundles move (orders of magnitude 2026: around CHF 20 for 7 days unlimited on Swisscom Prepaid Flat 7, Salt and Sunrise in the same band). Recheck the shop poster, not a 2025 screenshot. A Swiss “unlimited” SIM sometimes throttles hotspot. Read the tethering line.
Liechtenstein is not automatic. A Switzerland pack on the comparison does not include Italy.
Switzerland eSIM price vs a local SIM for 7 days
A 7-day Switzerland eSIM is priced per phone, in euros, promo deducted. Two compatible adults: two plans. The data calculator stops you buying 20 GB for a maps-and-messages city break.
The local SIM is paid in francs, plus sometimes a kit. A voice number has a price. Twenty GB at CHF 25 can beat a 5 GB eSIM at €15. Three GB of eSIM for a weekend often beat the queue and the cash exchange.
Do the sum once: N times the eSIM from the Switzerland comparison, against the Swisscom / Sunrise / Salt poster that day. Once every pocket can take eSIM and WhatsApp is enough, the nano-SIM almost always loses on a short stay.
Switzerland eSIM or local SIM by itinerary
Zurich + Lucerne, 8 days, a couple, two iPhones. Two eSIMs. No 11 p.m. queue. Hotspot only if a laptop at night, and only if the pack says so.
Alps + need to call hotels on a local number. One Swisscom SIM at the counter (or in town the next day) for the number. A data eSIM on the second phone if you want to stay online without draining the voice SIM.
Locked work phone. Official plastic SIM, or corporate roaming if Switzerland is truly on the plan (in Europe on *your* line, not only “EU roam like at home”). Do not buy a QR the handset will refuse.
Line up a Switzerland eSIM with a Swisscom, Sunrise or Salt shop
Our table ranks eSIMs. It does not list franc shop prices.
- If the phone takes eSIM, open the Switzerland page. Filter hotspot only if you share.
- Note the paid price (promo applied) for one pack, or for N packs.
- Put that total next to the shop poster, same GB and same days. The local SIM only wins if you need a +41, huge volume, or a phone without eSIM.
- Off the plateau, prefer an eSIM pack that writes Swisscom. A Sunrise city SIM does not catch a Swisscom eSIM in the valley.
How to choose between a Switzerland eSIM and a Swiss prepaid SIM
- Compatibility: the tool first. No = plastic SIM or Pocket WiFi, not a QR.
- Need a Swiss number: yes = official shop. No = eSIM if the phone takes it.
- Operator column on the Switzerland comparison against the counter brand (Swisscom, Sunrise, Salt).
- Paid price against today’s franc poster. Ignore the struck-through eSIM shopfront.
Switzerland eSIM and local SIM sources

- Salt Prepaid Salt prepaid. Airport shop hours: confirm before a late flight.
