Good to Know
- Mobile coverage in Grimentz is reliably available (Sunrise 4G verified), making mobile-based internet a viable backup or primary option if home broadband setup is slow.
- Switzerland is expensive for mobile data—local prepaid SIMs are significantly cheaper than international roaming. Get one on arrival.
- Home broadband setup typically takes 2–4 weeks; consider a mobile hotspot plan during initial stay while waiting for technician.
- e-SIM is convenient if purchased before arrival, but Swiss operators do not sell e-SIMs in-country; international providers (Simbye, Ubigi, Holafly, Airalo) are your only e-SIM option on arrival.
- Fiber availability in small alpine villages is inconsistent—check address-level availability with Swisscom, Sunrise, or local cable operators before signing a contract.
- 4G is nearly universal; 5G is expanding rapidly in cities and main valleys but less ubiquitous in remote areas. 4G is reliable for remote work across the country.

Connectivity Reliability Tier Rationale
Verified Sunrise mobile 4G coverage in Grimentz; widespread fiber rollout and reliable DSL/cable infrastructure across Switzerland; redundant mobile networks (Swisscom, Sunrise, Salt) provide fallback; however, fiber availability in this specific alpine village requires address-level confirmation.

- Fiber Optic Availability
