MobileSIM eSIM Data Plans for Saint Lucia

MobileSIM does not provide an unlimited data eSIM for Saint Lucia. Instead, it offers fixed‑data plans with different capacity limits and validity periods. For example, a 20 GB plan is available for 30 days at $66.00 USD, a 10 GB plan for 30 days at $45.00 USD, a 5 GB plan for 30 days at $25.00 USD, and a 5 GB plan for 60 days at $35.00 USD. Choosing a fixed data plan can be more cost effective for most travelers unless they intend to consume significant amounts of data.

MobileSIM does not provide a Saint Lucia eSIM that includes a local phone number or SMS capability. Only data‑only plans are available through this provider. Users can still communicate on the island by using internet‑based messaging and calling services such as WhatsApp, Telegram, or iMessage over the eSIM’s data connection.

MobileSIM lists four single‑country data plans that include Saint Lucia, and eight multi‑country plans that cover the island as part of a broader regional package. The available packages range in price from $2.34 to $66.00 and offer data caps between 200 MB and 20 GB, with validity periods spanning from 5 to 60 days.
