eSimfly eSIM Data Plans for Saint Lucia

eSimfly does not provide a truly unlimited data eSIM for Saint Lucia. All plans that carry “Unlimited” in the name offer a fixed daily data allowance—1 GB per day on the Saint Lucia plans and 3 GB per day on the Caribbean Islands plan. Once the daily cap is reached, the speed is reduced, but the plan is not truly unlimited in high‑speed data usage.

If a traveler prefers a larger data pool, eSimfly offers fixed‑data plans such as the 20 GB for 30 days plan or the 10 GB for 30 days plan. These plans provide predictable data usage without daily limits and can be more cost‑effective for users who need more than the daily caps of the “Unlimited” plans.

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.

eSimfly offers 13 single‑country plans that cover Saint Lucia and an additional 16 multi‑country plans that also include Saint Lucia in their coverage network. The available plans vary in price from around $7.69 to $221.94 USD, with data caps ranging from 1 GB to 20 GB. Some plans provide a fixed data amount, while others implement a daily data cap, offering flexibility based on travelers’ usage patterns.
