Best & fastest internet in Switzerland (2025) — providers, speeds and prices

Want the fastest internet in Switzerland? This guide compares Swisscom, Salt, Sunrise (and others), shows real top speeds (including 10 Gbit/s offerings), outlines typical prices, and explains how to pick the right plan for your home or small office.

Switzerland’s fixed-line market has changed fast: fibre rollouts and aggressive retail packages mean “gigabit” is no longer niche — and in some places you can even sign up for 10 Gbit/s. But “fastest” isn’t just a headline number: real speed, upload symmetry, latency and local availability all matter. Below I explain which providers offer the top raw speeds today, what those plans typically cost, and how to choose the best option for your needs.

Who offers the fastest speeds?

• Salt has marketed consumer fibre plans that push into the multi-gigabit range (advertised 10 Gbit/s consumer product). This makes Salt one of the fastest marketed consumer offers in Switzerland.

• Swisscom operates the country’s largest fibre backbone and advertises connectivity up to 10 Gbit/s for homes in supported areas — strong infrastructure and wide coverage.

• Sunrise (and its cable/fibre distribution partners) commonly sell up to 1 Gbit/s for residential customers; they emphasise wide availability and competitive bundles.

Bottom line: if you want headline top speed (10 Gbit/s) check Salt and Swisscom availability at your exact address. For 1 Gbit/s mainstream coverage with good value and TV bundles, Sunrise and other cable ISPs still compete strongly.

Speed vs experience — why raw Gbit numbers aren’t everything

A plan that says “10 Gbit/s” sounds impressive — but for most households a stable 1 Gbit/s symmetrical connection is already more than enough for streaming, large cloud backups, 4K gaming and multiple users. Consider:

• Latency (ping): online gaming and real-time apps need low latency; fibre is best here.

• Upload speed: content creators and cloud backups benefit from symmetric (equal upload/download) speeds — fibre usually delivers this.

• Router & Wi-Fi: the fastest plan is wasted if your router or home Wi-Fi can’t handle it. Invest in a modern Wi-Fi 6/6E router.

• Real-world throughput: congestion, peering and home wiring affect real download/upload speeds.

In Switzerland, fibre-to-the-home (FTTH) reliably gives the best latency and symmetric speeds compared with legacy copper or older cable technologies.

Providers, plans and typical prices (what you can expect)

Below are the common consumer choices and indicative prices you’ll see in 2025. Availability and promotional offers change quickly — always check the provider site for address-specific availability before you sign.

Salt (fast & aggressive pricing)

Salt positions itself as a disruptor in fixed broadband. Salt Home (fibre) is sold at highly competitive prices — promotional pricing as low as CHF 39.95/month (with a Salt mobile bundle) and CHF 49.95/month without a mobile tie-in for standard Salt Home offers; Salt has also rolled out multi-gigabit (10 Gbit/s) fibre products in select areas. Contracts commonly include a 24-month minimum and free activation promotions appear frequently.

Who it’s for: value-minded households, mobile+home bundle shoppers, and anyone who wants to try multi-gigabit offerings where available.

Swisscom (nationwide fibre backbone — up to 10 Gbit/s)

Swisscom offers multiple “blue Internet” speed tiers; the mid/high tier allows 1 Gbit/s and Swisscom advertises that its fibre network can provide up to 10 Gbit/s in supported locations. Retail entry prices for their 1 Gbit/s tier have been promoted from around CHF 59.90/month (promotional first-year offers exist; long-term price may differ). Swisscom also bundles TV and security features and provides a high-end Internet Box router option for fibre.

Who it’s for: users who want the widest fibre availability, strong service support, and premium add-ons (TV, smart home integrations).

Sunrise (broad availability, solid 1 Gbit/s plans)

Sunrise (including its cable partners) makes up to 1 Gbit/s a standard residential offering in many Swiss cities. Sunrise highlights speed tiers up to 1 Gbit/s for home customers and offers combined Internet+TV packages. Note that Sunrise implemented price adjustments in 2025, so final monthly fees may have seen modest increases.

Who it’s for: households wanting balanced value, reliable 1 Gbit/s performance and bundled TV/phone options.

Other options worth checking

• Regional FTTH providers and resellers: many local fibre providers (e.g., Init7, iWay, Teleboy and smaller municipal networks) sell 1 Gbit/s or even competitive multi-gig plans — often cheaper than national carriers in their areas. Comparison sites list several sub-CHF 50 1 Gbit/s offers in 2025.

Tip: local ISPs sometimes have better promotional pricing and more personalised support for rural addresses.

Price comparison (indicative — verify on provider sites)

These figures are representative; current promotions or address checks may show lower or higher rates. Always confirm activation fees, router costs and minimum contract durations.

How to choose the right plan (step-by-step)

1. Check availability at your address. Fibre rollout in Switzerland is advanced but not universal; a provider’s website will confirm if FTTH or cable is available where you live. (Most providers require an address check during order.)

2. Decide how much upload you need. If you upload large videos, host services or run heavy backups, prefer symmetrical fibre (many Swiss plans give symmetric speeds).

3. Consider router/Wi-Fi costs. Promotional prices sometimes exclude the modem/router or charge a one-off fee. For multi-gigabit plans, a modern Wi-Fi 6/6E router and wired Ethernet are recommended.

4. Compare bundles if you want TV/phone. Swisscom, Sunrise and many resellers bundle TV packages which may make a perceptionally more expensive plan better value.

5. Read small print on speed guarantees and throttling. Look for advertised “up to” vs. guaranteed throughput and any traffic management policies.

6. Ask about installation fees and delays. Fibre installation may involve a one-off activation or hardware fee and lead times variable by region.

Who should pick which provider?

• You want maximum headline speed (10 Gbit/s where available): Check Salt and Swisscom first. Salt has aggressively marketed consumer 10 Gbit/s products; Swisscom also advertises up to 10 Gbit/s on its fibre network. Availability is address-dependent.

• You want best nationwide coverage and support: Swisscom. Its national fibre footprint and service network are the widest.

• You want best value for 1 Gbit/s: compare Salt, regional resellers and promotional offers — many 1 Gbit/s plans can be found under CHF 50/month with bundles.

• You want bundled TV/phone and easy packages: Sunrise and Swisscom have broad bundle choices; Sunrise often promotes strong combined deals.

Final recommendations & next steps

1. Run an address check on Salt, Swisscom and Sunrise — speed and price differ by street. (Swisscom and Sunrise both provide address checking tools on their sites.)

2. Compare total cost of ownership — activation fees, router cost, contract length and early-termination penalties. Promotional monthly prices can change once the promo ends.

3. If you work from home or create content, prioritise upload symmetry and low latency. Fibre plans (not older cable or DSL) will serve you best.

4. Consider local resellers (Init7, Teleboy, iWay and regional networks) — they sometimes offer excellent prices and personal support in limited areas.
