Keep On Roaming does not provide a truly unlimited high‑speed data plan for the United States of America. All of its U.S. plans are capped at a fixed data amount. The offerings that carry “Unlimited” in the name actually provide 1 GB per day (or 1 GB total for the 1‑day plans) and then reduce the speed once the limit is reached; no plan offers unlimited high‑speed data without a cap.
For travelers who need more data, Keep On Roaming sells fixed‑data eSIMs such as the KOR-US‑20000MB‑30D plan with 20 GB for 30 days, the KOR-US‑50000MB‑30D plan with 50 GB for 30 days, and the KOR-US‑100000MB‑30D plan with 100 GB for 30 days. These plans provide a larger data allocation but are still limited; they do not qualify as unlimited.
