MobileSIM eSIM Data Plans for Saint Lucia

MobileSIM does not provide an unlimited data eSIM plan for Saint Lucia. The provider offers fixed‑data options instead. For example, a Global 20 GB plan is valid for 365 days and costs $69.00 USD, while a Global 10 GB plan is valid for 180 days and costs $59.00 USD. Smaller local plans include a Saint Lucia 5 GB option for 30 days at $32.50 USD and a Saint Lucia 3 GB option for 30 days at $21.00 USD. Choosing a fixed data plan can be more cost effective unless a user is an extremely heavy data consumer.

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 provides four single‑country plans and seven multi‑country plans for Saint Lucia. The available packages range in price from about $1.50 to $69 and in data capacity from 200 MB up to 20 GB, with validity periods that can last from 7 days to 365 days. Single‑country plans focus exclusively on Saint Lucia, while multi‑country plans bundle Saint Lucia coverage with other Caribbean destinations.
