Viasimo does not provide a truly unlimited high‑speed data eSIM for Switzerland. All Viasimo plans that use the term “Unlimited” in their name give a fixed daily allowance of 2 GB at full speed, after which the speed is throttled (to 1 Mbps for Swiss‑only plans or 384 Kbps for global plans). For travelers who need more data without reaching a throttle, Viasimo offers larger fixed‑data plans such as the 100 GB, 180‑day plan, the 50 GB Swiss plans with 30‑ or 180‑day validity, or a 50 GB European plan with 90‑day validity. These large‑data plans are generally more cost‑effective for high‑usage travelers compared to purchasing multiple small‑data “Unlimited” bundles.
