- Zermatt, Grindelwald, Verbier, Engelberg, St. Moritz, Davos: 5G or strong 4G in resort areas.

Switzerland eSIM vs a local SIM card
Swisscom, Sunrise and Salt sell prepaid SIMs, and Swiss law requires ID registration for every prepaid SIM. A travel eSIM is bought online and installed before you fly, connects to Salt and Sunrise when you land, and leaves your home SIM in the phone for calls and texts. The eSIM is data-only, so there is no local number. Phone settings (data roaming, keeping your number) are covered step by step in how to use an eSIM abroad.
Every tier of the Europe eSIM includes Switzerland, which matters because Switzerland is outside EU roaming rules.

Frequently asked questions
Can I use my US phone in Switzerland?
Yes, if it is unlocked and supports eSIM. Install the Switzerland eSIM before you fly for data, and keep your US line on for calls and texts with data roaming off, which avoids a daily carrier roaming fee.
What is the best eSIM for Switzerland?
The Flysimio Switzerland eSIM: it runs on Salt and Sunrise and costs $5.95 for 5 GB / 30 days, against $12.50 at Nomad when we checked on November 6, 2026. It covers the cities, the scenic rail routes and the main ski and hiking resorts. Hotspot is included and it is refundable within 7 days if unused.
Does a Europe eSIM work in Switzerland?
Not always: Switzerland is outside the EU, so some Europe eSIMs leave it out. Every tier of the Flysimio Europe eSIM includes Switzerland, so a Switzerland + France or Italy trip runs on one plan ($7.05 for 5 GB / 30 days).
What if the eSIM does not work for me?
You can get a full refund within 7 days of purchase if the eSIM is unused or has used less than 100 MB, so you can install it and check it connects first. Full terms are in our refund policy.
Does the eSIM work on the Glacier Express and Bernina Express?
Yes. Salt and Sunrise have 4G along the Glacier Express (Zermatt to St. Moritz) and Bernina Express (Chur to Tirano). Some short Bernina tunnel sections have brief gaps, but coverage is excellent overall.
Is Zermatt well covered?
Yes. Zermatt village has 5G. The cable car to Klein Matterhorn (3,883m — the highest in Europe) has 4G at the summit station; high glacier terrain above may drop to 3G.
What about Jungfraujoch (Top of Europe)?
Salt and Sunrise have 4G at Jungfraujoch (3,454m). The cogwheel train through the Eiger and Mönch tunnels has coverage at stations; sections between stations may drop briefly.
Does my Switzerland eSIM work in Liechtenstein?
Yes. Liechtenstein uses Swiss carrier networks, so your Switzerland eSIM works seamlessly in Vaduz and throughout the principality.
