There are no truly unlimited data eSIM plans for Turks and Caicos Islands offered by eSIMCard. The plans that use “Unlimited” in their names provide a fixed amount of high‑speed data—most of them 1 GB per day or total for the validity period—and once that amount is used the speed is reduced to 500 kbps (or 2 Mbps for some “Unlimited Plus” variants). Because of the cap, these plans are not unlimited in the sense of offering unrestricted high‑speed data.
If you need a larger data allowance, eSIMCard offers fixed data plans such as 50 GB for 30 days priced at $194.37 USD or a 100 GB plan for 180 days at $478.46 USD. These plans give you higher data limits without the speed throttling that occurs on the “Unlimited” plans, and can be a more cost‑effective choice if you anticipate heavy data usage.
