How Does SIM Card & Internet Work in Switzerland?

Last verified: 2025-06 · Europe

1The Quick Answer

🚨Warning

Switzerland is not in the EU, so EU roaming rules do not apply — buy a local SIM or eSIM for data; Swisscom has the best coverage including in mountain areas.

2What You Need to Know

Switzerland's exclusion from the EU means that EU mobile roaming agreements do not apply — tourists with EU SIM cards will likely incur roaming charges or data cutoffs depending on their plan. Local operators are Swisscom (premium coverage including remote Alpine areas), Sunrise, and Salt. Tourist SIM cards are available at airports, post offices, and phone shops. Airalo and other eSIM providers offer convenient Switzerland data plans. Mobile coverage across Switzerland is excellent by global standards — even many mountain cable car stations and hiking trails have 4G coverage thanks to infrastructure investment.
