RedEx eSIM does not provide a truly unlimited data eSIM for Saint Barthélemy. The plans that carry the name “Unlimited Data” actually have a hard data cap of 1 GB, 2 GB, or 3 GB per day, and once that amount is reached the speed is reduced to 384 kbps or 5 Mbps. Therefore, the data is not unlimited.
If a larger data allowance is needed, RedEx eSIM offers fixed data plans such as 50 GB for 3 days, 5 days, or 7 days. These plans give a set amount of high‑speed data that must be used within the validity period. Choosing a fixed data plan can be more cost‑effective for most travelers unless very heavy data usage is expected.
