RedSim does not provide a truly unlimited data eSIM for Barbados. The only plan that carries “Unlimited” in its name, Caribbean Unlimited 7 Days, actually supplies 3 GB of high‑speed data per day and then throttles the remaining traffic to 1 Mbps, so it is not an unlimited plan.
Travelers who need more data can choose from RedSim’s fixed data plans that are valid for 30 days, such as Global 20GB 30 Days, Barbados 20GB 30 Days, Global 10GB 30 Days, Caribbean 10GB 30 Days, or the Barbados 10GB/day 1 Day plan. These plans offer a set amount of high‑speed data and are available for the specified validity period. Selecting a fixed data plan can be more cost‑effective for most users unless they require very high data usage.
