Do I pay extra to use my phone in other EU countries with a plan from Switzerland?
Switzerland is outside the EU roaming area, so «roam like at home» and EU price caps do not apply to Swiss SIM cards. Swiss rules apply: roaming works only after a cost limit is set, and use is billed per second and per kilobyte.
With a plan from an operator in the EU or EEA, calls, texts and data in other EU and EEA countries are generally charged as at home, within fair-use limits. Other rules apply to plans from other countries; what applies with a plan from Switzerland is below.
📜 The rules in Switzerland
The details
- When your phone joins a foreign network, your provider must tell you immediately and free of charge the maximum cost of calls, texts and data. You can switch this message off and on (Art. 10a FDV). (fedlex.data.admin.ch)
- Providers must offer roaming options. You choose the start date, they stay valid for at least 12 months, and you can buy them free of extra charge online, in Switzerland or abroad (Art. 10d FDV). (fedlex.data.admin.ch)
- Near the border your phone can join a foreign network without you noticing. Switch roaming off in your settings to avoid charges. For a surprise bill, talk to your provider, then go to ombudscom. (bakom.admin.ch)
ombudscom – Schlichtungsstelle Telekommunikation
Official telecom dispute body: mediates between you and your provider once your complaint to the provider has failed. You pay a CHF 20 handling fee. Phone line for questions on the procedure, working days 10:00–13:00.
Bundesamt für Kommunikation (BAKOM)
Federal telecoms authority for complaints under public telecom law, such as universal service, emergency call routing, value-added numbers, spam and free choice of provider. If it finds a breach, it can open supervisory proceedings or, for example, withdraw a number.
🪜 Step by step
- Check your plan before you travelSee which countries your plan treats like home and whether it has a separate data allowance abroad.
- Read the welcome messageWhen you arrive, your operator usually sends a message with the prices and limits that apply.
- Watch the fair-use limitUnlimited or very large data plans can have a smaller allowance abroad. Above it, a surcharge can apply.
- Take care on ships, planes and near bordersThere your phone can connect to a network outside the usual roaming rules. Switch off roaming or use flight mode when in doubt.

❓ Questions
What does fair use mean?
Operators may limit roaming at home prices to normal travel, not living abroad for good, and may cap data abroad on very large plans.
Which countries count as home?
That depends on your plan and on where your operator is based. The rules for Switzerland are on this page.
Are calls back home free?
Calls home usually cost the same as at home when roaming at home prices applies. Calls to other countries can cost extra.
