MobiMatter eSIM Data Plans for Saint Lucia

MobiMatter does not offer an unlimited data eSIM plan for Saint Lucia. Travelers can instead choose from fixed-data options. The provider sells several 10GB and 20GB plans that are valid for 30 days and allow tethering.

A notable choice is the Caribbean 20 GB plan, priced at $74.99 USD, which covers Saint Lucia and 21 other countries. Another option is the Americas 20 GB plan, costing $84.99 USD and providing coverage in Saint Lucia plus 35 additional countries. Choosing a fixed plan can be more economical for most users unless one expects extremely heavy data usage.

MobiMatter does not provide any Saint Lucia eSIM plans that include a local phone number or SMS capability. Customers can only purchase data‑only eSIMs from this provider. For voice and messaging needs, travel‑ready applications such as WhatsApp, Telegram or iMessage can be used over the available data connection instead of relying on a traditional SMS service.

The provider offers 17 multi‑country eSIM plans that cover Saint Lucia, with prices ranging from $5.49 to $84.99 and data caps between 1 GB and 20 GB. Plan validity varies from seven to thirty days, and most of the options allow tethering. No single‑country‑only plans are available for Saint Lucia.
