How to Avoid Roaming Charges in Switzerland

Updated May 11, 2026 · Jules de Bruin, Editor

Updated May 2026. Switzerland is not in the EU — so "Roam Like at Home" does not apply. Most German prepaid and contract tariffs charge zone-1 rates in Switzerland (typically €0.49-0.99 per MB) which can rack up €30-50 in extra charges over a single weekend. The fix: pick a provider that includes Switzerland by default. Telekom prepaid, fraenk, KAUFLAND MOBIL, and NORMA connect all bundle Switzerland in zone-1 roaming without surcharge.

FAQ

Which German providers include Switzerland for free?

These providers treat Switzerland as zone 1, no surcharge for normal use:

Telekom prepaid — prepaid overview explicitly calls out Switzerland alongside EU and UK
fraenk — homepage states "EU + Switzerland" roaming on the €10/month plan
KAUFLAND MOBIL — price list shows Switzerland in zone 1 pricing
NORMA connect — same congstar stack as KAUFLAND, Switzerland zone 1
congstar prepaid — Switzerland data roaming appears in prepaid detail text on some tariffs

Which German providers sell Switzerland separately?

Vodafone CallYa — Switzerland is a paid roaming option
O2 Prepaid — Switzerland generally treated as paid roaming zone
1&1 contracts — Switzerland add-on sold separately
Most supermarket prepaid (LIDL Connect, ALDI TALK, ja! mobil, Penny Mobil) — verify per tariff; usually paid roaming
Diaspora MVNOs (Lebara, Lyca, Ortel, AY YILDIZ) — verify per tariff

If your provider sells Switzerland separately, expect to pay €0.49-0.99 per MB for data and €0.99-1.99 per minute for calls. Even moderate use (Google Maps for 2 hours, 1 hour of WhatsApp video) easily costs €30-50 per day.

Alternatives if your provider doesn't include Switzerland

Three workarounds, in order of cost:

Buy a separate Swiss eSIM. Holafly, Saily, Airalo, Ubigi all sell Switzerland-only data eSIMs. A 5-day unlimited Holafly Switzerland eSIM typically costs ~€25; cheaper bundles via Saily and Airalo start ~€5.
Use WiFi only. Switzerland has extensive cafe and hotel WiFi. Disable data roaming entirely on your phone before crossing the border.
Add a Switzerland day-pass on your German tariff. Vodafone, O2, and Telekom all sell day-passes for ~€3-5 per day. Cheaper than per-MB rates if you only need data occasionally.

Frequently asked questions

Why isn't Switzerland in EU roaming?

Switzerland is not an EU member state. The EU's "Roam Like at Home" rules only apply to EU/EEA countries: the 27 EU members plus Iceland, Liechtenstein, and Norway. Switzerland is in the European Free Trade Association (EFTA) but never joined the EU or EEA, so EU mobile rules don't cover it.

Which is cheapest: free-Switzerland tariff or paid day-pass?

Free-Switzerland tariff wins if you cross the border more than once or twice a year. Switching to Telekom Prepaid M or fraenk costs €10-15/month. A Vodafone CallYa Switzerland day-pass costs €3-5/day. Three Swiss day-trips a year = breakeven; more than that, the free-Switzerland tariff is cheaper.

Does "Switzerland in zone 1" mean unlimited?

No. It means Switzerland is treated the same as your normal Germany allowance. If you have 20 GB Germany allowance and use 5 GB in Switzerland, you have 15 GB left for the rest of the cycle. Fair-use limits typically apply if you stay in Switzerland for an extended period.

What about Liechtenstein, Norway, Iceland?

All three are in the EEA — "Roam Like at Home" applies on every German tariff. No special tariff needed. Same applies to Iceland and Liechtenstein. Only Switzerland is the awkward one.
