eSIMCard does not provide a truly unlimited data eSIM for United States of America. Every plan listed contains a fixed data cap; for example, the plans named “Unlimited” supply only 1 GB (or 2 GB) of high‑speed data per day, after which the speed is throttled to 512 kbps or 2000 kbps respectively.
Travelers who need a large, unrestricted amount of data can choose from eSIMCard’s fixed‑data packages, such as the 100 GB plan valid for 30 days or the 100 GB plan valid for 180 days, which keep the full data allowance available for the entire validity period before the plan expires. These options can be more cost‑effective for heavy data users than plans that reduce speed once a daily quota is reached.
