Wholesale Switzerland Data SIM Cards on Sunrise & Salt

Local Switzerland MNO data SIM and eSIM solutions for B2B projects

Global Data Fire supplies Switzerland data SIM cards and Swiss eSIM solutions for companies that need reliable mobile data across Switzerland. Our wholesale offer covers Sunrise unlimited data SIM and Salt unlimited data SIM plans.

Available in physical SIM and eSIM (QR profile) formats — for SIM banks, cloud SIM platforms, routers, MiFi devices, IoT/M2M equipment, fleet and logistics, field teams and enterprise connectivity.

Sunrise or Salt — how buyers usually decide

• Sunrise — the larger challenger network with a broad national footprint including smaller cantons and mountain valleys, typically chosen where coverage consistency outside the main cities matters.
• Salt — strong performance in the urban belt (Zurich, Geneva, Basel, Lausanne, Bern) and commonly the more cost-efficient route for high-volume unlimited data in city deployments.
• Fair-use matters more here — because both offers are unlimited, the meaningful commercial difference is the fair-use or speed-management threshold, not the bucket size. We confirm the exact terms in every quote.

Why a local Swiss SIM instead of relying on an EU SIM in Switzerland

Switzerland is outside the EU, so EU roam-like-at-home bundles frequently exclude it or bill it at a separate rate. For any project with continuous Swiss usage — offices, construction sites, events, logistics on the Gotthard and Zurich–Geneva corridors — a local Sunrise or Salt SIM gives predictable domestic throughput rather than depending on an EU SIM that may be throttled or surcharged when used in Switzerland. Alpine terrain also means coverage varies by valley and altitude far more than in flat European markets, which is a coverage-testing question rather than a plan-size question.

Typical Swiss deployments

• • Enterprise failover — unlimited backup WAN for finance, pharma and professional-services offices.
• • Events & temporary sites — congress, sports and construction connectivity where fixed lines are impractical.
• • Router & MiFi fleets — hotspot-enabled unlimited SIMs for mobile teams across cantons.
• • IoT / M2M — monitoring and industrial gateways in a high-value, low-tolerance-for-downtime market.

Delivery and activation

Physical SIMs are shipped internationally for router and fleet installations; eSIM (QR profile) is available depending on operator and device support. Activation and lead times are confirmed per project — we reply within one business day.

Frequently asked questions

Do your Switzerland SIMs use Sunrise or Salt?

Both. Global Data Fire supplies wholesale Switzerland data SIM cards on Sunrise and Salt — two leading Swiss MNOs — with unlimited data plans for B2B customers.

Are unlimited plans subject to fair-use limits?

Some Swiss unlimited plans may be subject to operator fair-use policies or speed-management thresholds after very high monthly consumption. Actual terms depend on the operator, plan tier and commercial agreement — we confirm the exact fair-use conditions in every quote.

Do Switzerland plans include EU roaming?

Our Switzerland SIM cards are local Swiss SIMs on Sunrise and Salt for use inside Switzerland. Switzerland is not part of the EU, which is why a local Swiss SIM is commercially important for reliable on-the-ground connectivity.

Are 5G and hotspot use supported?

Yes. Sunrise and Salt both operate 5G networks across Switzerland, and the plans support hotspot / tethering for routers and MiFi devices. Actual 5G availability depends on operator rollout, device compatibility, location and plan configuration.

Which Swiss cities are covered?

Nationwide coverage including Zurich, Geneva, Basel, Bern, Lausanne and the wider Swiss cantons on both Sunrise and Salt.
