eSimfly eSIM Data Plans for Saint Lucia

eSimfly does not offer a truly unlimited data eSIM for Saint Lucia. The only plan listed with an “Unlimited” designation is the Caribbean Islands Unlimited 7 Days, which actually limits users to 3 GB per day, so it is not unlimited high‑speed data.

Users looking for high‑capacity options can choose fixed‑data plans instead. For example, eSimfly offers a 20 GB plan valid for 30 days and a 10 GB plan also valid for 30 days to travelers in Saint Lucia. These fixed‑data packages provide a larger data allowance and can be more cost‑effective for heavy data users than relying on a daily capped plan.

eSimfly does not offer any Saint Lucia eSIM plans that include a local phone number or SMS capability. Users can only purchase data‑only eSIMs from this provider. However, the data connection can be used with VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages without a traditional phone number or SMS support.

In Saint Lucia, eSimfly provides six single‑country plans and sixteen multi‑country plans. The plans cover data caps from 1 GB to 20 GB and are priced between $8.93 and $134.53. One plan follows a daily data‑cap model, while the remaining plans are fixed data‑cap, allowing customers to choose between short‑term daily limits or longer‑term static data amounts.
