Lotso Travel’s eSIMs for Switzerland that contain “Unlimited” in the name do not provide truly unrestricted high‑speed data. Each of those plans has a specified daily data allowance—such as 1GB/day, 2GB/day, or 3GB/day—and once that amount is used the speed is throttled to a lower rate such as 128kbps, 384kbps, or 5.1 Mbps.
If you need a larger amount of high‑speed data without a speed reduction, Lotso Travel offers fixed data plans with generous caps, for example the 50GB eSIM that is valid for 5 to 30 days and the 90GB eSIM valid for 30 days. These plans keep full speed throughout the period and may be more cost‑effective for heavy data use.
