Good to Know
- Switzerland is not in the EU, so EU roaming protections do not apply; roaming charges to nearby EU countries are expensive and uncapped—obtain a local Swiss SIM or e-SIM immediately upon arrival rather than relying on foreign roaming.
- e-SIM is often cheaper and more convenient than physical prepaid SIM cards at airports; purchase online before departure and activate on arrival via QR code (takes <5 minutes).
- St. Moritz and Alpine regions are reliably covered at 4G/4G+ speeds; 5G is sparse outside major urban corridors; for mountain activities and remote areas, expect 4G as the realistic floor.
- Fixed broadband (fiber/cable/DSL) offers superior reliability and speed compared to 4G/5G home internet; prioritize fixed-line if staying in one location long-term.
- Swisscom has the most extensive rural and Alpine coverage; Sunrise offers competitive urban/suburban performance; Salt is budget-friendly but slightly behind in coverage breadth.
- Swiss SIM cards and plans are generally expensive by EU standards, but salaries are correspondingly high; e-SIM travel providers often offer better per-GB value than local prepaid SIMs, especially for short-term stays.

Reliability Context
- Outage Patterns
- No major documented widespread outage patterns reported; infrastructure rated as highly reliable
- Fiber Vs Wireless
- Fixed-line (DSL/fiber) superior speeds and stability vs 4G/5G home broadband; fixed wireless (mobile home internet) useful fallback in remote locations but not recommended as primary for consistent remote work
- Mountain Alpine Caveat
- St. Moritz region (Engadin Valley, Grisons) experiences occasional signal strength variations due to terrain; remote hiking areas may have weaker signal; 5G is not guaranteed outside urban core; fixed wireless (4G/5G home) connections less consistent than fixed-line in Alpine areas
- Universal Service Framework
- Switzerland guarantees universal service obligation for basic broadband (affordable, reliable, certain quality standard) via Swisscom; OFCOM (Federal Office of Communications) regulates and monitors
