How many travellers?
You do not get a new phone number with this eSIM.
Setting up your eSIM? The installation and activation guide walks through it step by step, and the full FAQ covers device compatibility, hotspot, dual SIM and topping up.
Switzerland sits outside the EU, so an EU eSIM usually will not cover it (or only at extra cost) - a dedicated Switzerland plan keeps things predictable. Install it before you travel, switch off airplane mode on arrival, and you are connected for the whole Alpine trip.
The eSIM connects when you turn off airplane mode at Zurich (ZRH) or Geneva (GVA). Your train ticket, maps and the SBB app are ready before you reach the platform - and in Switzerland the train is almost always the next step.
Switzerland's networks (Swisscom, Sunrise and Salt) are among Europe's best, with 5G in the cities and strong coverage through the valleys and resort towns - Zermatt, Interlaken, Lucerne. You stay online on the scenic rail routes like the Glacier Express and the Jungfrau line for most of the journey, with drops only in the long Alpine tunnels and on high, remote peaks.
Switzerland is outside the EU, which is why EU carriers' roaming does not cover it - but most UK networks include it anyway: EE, O2, Vodafone, Three and Tesco Mobile all count it in their Europe zone. The exceptions catch people out: giffgaff charges its rest-of-the-world rates there, SMARTY charges per megabyte, and iD Mobile does not include it at all. Check yours in the table below before a ski week in Verbier or Zermatt.
Switzerland follows the Schengen rules, and your GHIC is valid there for medically necessary state healthcare. If you drive, you must buy and display a motorway vignette (gov.uk, updated 11 August 2026). One more thing to pack: Swiss sockets are type J, used only in Switzerland and Liechtenstein, and a UK plug will not fit - a standard European two-pin adaptor usually works in them.
Often not - Switzerland is outside the EU, so many EU plans exclude it or charge extra. A dedicated Switzerland eSIM avoids that.
Yes for most of the route - coverage through the valleys and resort towns is strong. Long Alpine tunnels and high remote sections can briefly drop signal.
On EE, O2, Vodafone, Three and Tesco Mobile, yes - in their Europe zones. On giffgaff, SMARTY and iD Mobile it is charged separately or not included (each network's own terms, 9 October 2026).
