SeferESIM does not provide an unlimited data eSIM for Barbados. All of the Barbados‑specific plans list a fixed data cap, such as 20GB for 30 days or 10GB for 30 days, and none of the data amounts is labeled as unlimited.
Travelers who need a large amount of data can choose one of the fixed data plans. For example, the Barbados 20GB 30Days plan is priced at $150.16 USD, and the Barbados 10GB 30Days plan is $81.80 USD. These plans offer a set amount of high‑speed data that must be used within the validity period, and they can be more cost‑effective for most users unless a very heavy data consumption is expected.
