eSIMCard’s plans that include “Unlimited” in the name are not truly unlimited high‑speed data. Each of these plans provides only 1 GB or 2 GB of high‑speed data per day and, after the cap is reached, the speed drops to a reduced level (for example, 512 kbps or 2000 kbps). The plans are marketed as “unlimited” in the sense that the data allowance does not stop, but the speed becomes throttled once the daily quota is used.
If you need a larger amount of unrestricted high‑speed data, eSIMCard offers fixed‑data plans such as a 50 GB plan valid for 30 days or a 35 GB plan also valid for 30 days. These plans give you a fixed data allowance without throttling, which can be more cost‑effective for travelers who use a lot of data.
