eSIMCard does not provide a true unlimited‑data eSIM for Switzerland. All plans that carry the word “Unlimited” in the name are limited to a fixed data allowance—ranging from 1 GB per day up to 2 GB per day—and include a reduced speed once that limit is reached (for example, throttled to 512 kbps or 2000 kbps). Because the data coverage is capped, the name “Unlimited” can be misleading; it only describes the ability to select different data packages, not unlimited high‑speed data without limits.
For travelers who need more data, eSIMCard offers a selection of fixed data plans with large capacities. Examples include a 50 GB plan, a 35 GB plan, and a 100 GB plan, each valid for 30 days (or longer for the 100 GB 180‑day option). These fixed‑data plans provide unthrottled high‑speed data and can be more economical for users who anticipate heavy data usage in Switzerland.
