eSIMCard does not provide a truly unlimited high‑speed data eSIM for Switzerland. All plans branded as “Unlimited” in the eSIMCard catalogue actually offer a fixed data allowance (typically 1GB or 2GB per day) that is subject to throttling once the limit is reached; the throttled speeds are listed as 500kbps, 512kbps, or 2000kbps in the plan details.
Travelers looking for larger high‑speed data packages can choose from eSIMCard’s fixed plans, such as the 50GB data plan valid for 30 days, the 35GB data plan also for 30 days, or higher‑capacity options like 100GB for 31 days. These plans provide ample data without the daily throttling that accompanies the “Unlimited” naming, and can be more cost‑effective for heavy data users.
