Horizon eSIM eSIM Data Plans for Saint Lucia

Horizon eSIM does not offer an unlimited data eSIM for Saint Lucia. All available plans for the destination have a fixed data allowance, such as 20GB for 90 days, 10GB for 30 days, or 5GB for 30 days, each priced in USD.

Customers who need larger data volumes can choose one of Horizon eSIM’s fixed plans. For example, the Global 20GB 90 day plan costs $309.12 USD, while the Caribbean 10GB 30 day plan costs $154.67 USD. Selecting a fixed data plan can be a more cost‑effective option unless a user requires truly unlimited data usage.

Horizon eSIM does not provide a phone number or SMS capability for Saint Lucia. Travelers using a Horizon eSIM in Saint Lucia will receive only a data‑only profile. For voice and messaging, apps such as WhatsApp, Telegram or iMessage can be used over the data connection, but some destinations may restrict or block certain VoIP services, so it is recommended that travelers confirm that the apps they depend on are accessible in Saint Lucia prior to purchase.

Horizon eSIM offers nine multi country plans that cover Saint Lucia, and does not provide a single‑country plan for the island. The available packages price between roughly $16 and $309, with data caps ranging from 1 GB to 20 GB, and validity periods from seven days up to a full year.
