eSIMCard does not offer a truly unlimited high‑speed data eSIM for Switzerland. All plans that carry the word “Unlimited” in their name actually provide a fixed data amount—such as 1 GB in a single day or 2 GB per day for a set number of days—and after that amount is reached the speed is throttled (for example to 500 kbps, 512 kbps, or 2000 kbps depending on the plan).
Travelers who need a larger or truly unlimited data allowance can choose from the provider’s fixed data plans. For example, a 50 GB plan is valid for 30 days and a 100 GB plan offers 90 days or 180 days of high‑speed data, all without the speed reductions that apply to the “Unlimited” plans. These data‑heavy options are generally more cost‑effective for users who expect to consume a lot of data while in Switzerland.
