eSIMCard does not provide a truly unlimited high‑speed data plan for Turks and Caicos Islands. All plans that carry the “Unlimited” label actually grant a fixed amount of data, such as 1 GB per day for up to 15 days; once the daily allowance is reached the speed drops to 500 kbps (or 2000 kbps for the “Unlimited Plus” versions). Because of this cap, the “Unlimited” plans are not considered limitless from a high‑speed standpoint.
Travelers who need a larger data volume can choose a fixed‑data plan instead: a 50 GB plan is available for 30 days at $194.37, and a 100 GB plan for 180 days is sold for $430.64. These plans offer a generous data allotment with no throttling once the limit is reached, making them more suitable for heavy‑usage users.
