Billion Connect does not provide an unlimited data eSIM for Saint Lucia. All listed plans have a fixed data cap, with the largest offering 100 GB for a 31‑day validity period. For travelers who need a high‑volume plan, the 100 GB 31‑day bundle (priced at $61.50 USD) and the 50 GB 31‑day bundle (priced at $46.00 USD) are available as fixed data plans. These larger bundles can be more cost‑effective for users with high data consumption, while the lower‑cap options remain available for lighter usage.
