eSIMCard does not provide a truly unlimited high‑speed data eSIM for Barbados. The plans that carry the word “Unlimited” in their names all include a capped allowance of 1 GB per day or 1 GB total for a single‑day period, and after the cap is reached the speed is reduced to 500 kbps (or 2000 kbps on some “Plus” variants). Therefore, users looking for continuous, non‑throttled high‑speed data will need to choose a plan with a fixed data allowance.
For travelers who require more data, eSIMCard offers larger fixed‑data options, such as 50 GB for 30 days or 100 GB for 180 days. These plans give you a set amount of high‑speed data without a daily renewal and without the speed reductions that appear on the “Unlimited” plans. Choosing a fixed data plan can provide better value for heavy data users.
