eSIMCard eSIM Data Plans for Saint Lucia

eSIMCard labels several plans as “Unlimited” for Saint Lucia, but these plans still carry a data cap. Each “Unlimited” package gives a maximum of 1 GB or 2 GB of high‑speed data per day, after which the speed is reduced to 500 kbps or 2000 kbps. For example, the Unlimited eSIM Data For 1 Day in Saint Lucia provides 1 GB of data, and the Unlimited Plus eSIM Data For 1 Day provides 2 GB before throttling begins.

If a traveler needs truly unlimited high‑speed data, eSIMCard offers fixed‑data plans instead. One example is the eSIM, 100 GB, 180 days, Global, Unthrottled package, and another is the 50 GB eSIM Data For 30 days in Saint Lucia. These plans give large unthrottled data allowances that can be more cost‑effective for heavy data use.

eSIMCard does not provide a Saint Lucia eSIM that includes a local phone number or SMS capability. The provider currently offers only data‑only eSIM plans for travelers heading to Saint Lucia. For voice or messaging, users can rely on internet‑based services such as WhatsApp, Telegram, or iMessage, which work over the data connection.

eSIMCard provides 19 single‑country data plans that include coverage for Saint Lucia, as well as 27 multi‑country plans that also cover the island. The available plans span a price range from roughly $7.93 to $430.64, with data caps between 1 GB and 100 GB and validity periods that can last from 1 day up to 365 days. Plan types vary: some offer a fixed data amount valid for the entire duration, while others impose a daily data cap that refreshes each day, allowing users to purchase a certain amount of data per day rather than a lump‑sum total. Several of these plans also permit tethering and, in some cases, allow reduced speeds (down to 500 kbps or 2000 kbps) when data is exhausted.
