The short verdict
For most visitors to Switzerland, Flysimio was the cheapest of the four providers we track at 5 GB when we checked in August 2026. One correction worth stating plainly: our Swiss plans route through Salt and Sunrise, not Swisscom. Swisscom has Europe's best mountain network, reaching the vast majority of Swiss hiking trails, ski pistes, and scenic rail routes like the Glacier Express and Bernina Express, so if your trip is built around back-country alpine hiking, pick on carrier rather than price. Zurich, Geneva, Bern, and Basel have full 5G on all three networks; Zermatt and Jungfraujoch have 4G at altitude.

How this table is priced. Flysimio prices are read live from our carrier catalog every time this page loads, so the figure here is the figure at checkout. Competitor prices are the US-dollar price shown on each provider's own site, read on the date in the last column and linked to the page we read it from; promotional prices are marked alongside the list price. Price per GB is the plan price divided by its included data — unlimited passes have no per-GB figure and are ranked by total price instead.

Swisscom has 4G at Jungfraujoch (3,454m). The cogwheel train through the Eiger and Mönch tunnels has coverage at stations; sections between stations may drop briefly.
