Switzerland is outside the EU. That changes the rate. Not the experience.
The European Union's regulated roaming caps don't apply in Switzerland — the country sits outside the bloc, so a foreign carrier roaming pass in Zurich often costs more than the same pass in Milan or Munich. Travelers crossing from Italy into Ticino or from Germany into Basel sometimes notice their daily roaming charge double on the same trip. The eSIM lives outside that structure: one rate per country, one rate for Switzerland.
Roamzy charges $1.02 per gigabyte in Switzerland. That's $0.0010 per megabyte, billed in real time as your phone uses data on Swiss networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 193 countries — that's the exact metered total, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor to Switzerland uses 0.4–1.2 GB per day: SBB Mobile constantly (Swiss trains run on a five-second tolerance and you check the app), Maps in Zurich and Lucerne, the camera-translator on a Rösti menu in German Switzerland or a French menu in Geneva, contactless payments via Apple Pay or Twint, the occasional video call. Mountain days run lower because you're often on a lift offline. Call it 1 GB/day for a city trip:
| Trip length | Roamzy ($1.02/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days | $3.07 | $25–55 | $15–35 + paperwork |
| 1 week | $7.17 | $45–110 | $25–45 + paperwork |
| 2 weeks | $14.34 | $80–180 (often two passes) | $35–60 + 30-day cap |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
Swiss SIM kiosks at ZRH or GVA are well organized but tourist tariffs reflect the broader Swiss price level — they're rarely competitive with the eSIM for a one-week trip.
Where does Roamzy work in this country?
Switzerland has one of the better-wired networks in Europe, with a famous caveat: the Alps. The shape on the ground:
- Zurich, Geneva, Basel, Bern, Lausanne — 5G in the centers, providers compete on quality
- Lucerne, Interlaken, St. Moritz, Zermatt, Davos — solid LTE in the towns; lifts and back-pistes drop
- SBB intercity trains — near-continuous signal end to end; brief drops in long tunnels (Gotthard Base is 57 km — expect a long quiet stretch)
- Mountain villages above 1,500 m — workable LTE in the village core, weaker on the trails
- Glacier 3000, Jungfraujoch, Matterhorn — patchy at the top; signal returns on the way down
- The lakes (Geneva, Zurich, Lucerne, Maggiore) — solid along the shores; ferries hold signal except mid-lake briefly
Why is per-megabyte pricing simpler than packages?
A Swiss trip is already cognitive load: a country with four official languages, train tickets that can be cheaper if you book a window in advance, a card your bank flagged on the first 50-CHF lunch. The data plan should not also be a problem.
Roamzy is built around that. No first-purchase promo. No fine-print throttling. No auto-renewal six months later. One rate, billed by the megabyte, balance carries.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|
| Type J | 230 V | 50 Hz | iPhone XS+ | Pixel 3+, Galaxy S20+ |
- Sign in to Roamzy via Telegram or Google
- Your first eSIM is free and comes with real data on us. After that, top up from $20 in stablecoins (USDT or USDC): no cards, no banks, no FX surcharges
- The QR code appears in your dashboard as soon as the eSIM is issued
- On the iPhone itself (iOS 17.4 or newer), tap Tap to install in the QR card; otherwise Settings → Cellular → Add eSIM → scan QR
- The counter starts the moment you land at ZRH, GVA, or BSL
Swiss plugs are Type J — a slim three-pin that's specific to Switzerland. Bring an adapter. Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
Three traps Roamzy doesn't have because they were never built in.
- No welcome promo that bait-and-switches your second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth cost the same $0.0010/MB.
- No auto-renewal you forgot to cancel. Balance runs out, the eSIM stops.
Swiss data here is metered at a low flat rate and then left alone: no expiry, no renewals, no small print. A price that carries nothing extra can't be undercut, so we don't bother with gimmicks.
What if my trip continues to other countries?
Switzerland sits at the heart of Western Europe. Same Roamzy account, same logic at the border:
- Italy — across the Gotthard or the Simplon, separate country rate
- France — TGV from Geneva to Paris, eSIM hands over without intervention
- Germany — frequent business extension via Basel and the ICE
