Monty eSIM eSIM Data Plans for Saint Lucia

Monty eSIM does not provide an unlimited data eSIM plan for Saint Lucia. The available plans for Saint Lucia are fixed‑data packages that offer 10GB, 5GB, or 3GB of high‑speed internet for 30 days. For example, the 10GB plan costs $55.99 USD, while the 5GB plan costs $29.99 USD. Choosing a fixed data plan can be more cost‑effective for most travelers unless they are extremely heavy data users who would otherwise exceed the limits of a capped plan.

Monty eSIM does not offer a Saint Lucia eSIM that includes a local phone number or SMS capability. The only eSIMs available from Monty for Saint Lucia are data‑only plans. Travelers can still use popular VoIP applications such as WhatsApp, Telegram and iMessage to make calls and send messages over the data connection.

Monty eSIM offers four single‑country data plans and five multi‑country plans that include Saint Lucia. The single‑country plans provide data caps from 1 GB to 10 GB and validity periods between 5 and 30 days, with prices ranging from roughly $7.50 to $56.50. The multi‑country plans also cover the same data cap and validity ranges, and they carry the same price range, but they are usable across several Caribbean destinations. These plans differ mainly in coverage: the single‑country options are restricted to Saint Lucia only, while the multi‑country plans allow roaming within multiple countries.
