Horizon eSIM eSIM Data Plans for Saint Lucia

Horizon eSIM does not provide an unlimited data eSIM for Saint Lucia. All plans listed for the island have a fixed data cap, with the largest offering 20 GB for 30 days.

Travelers who need a substantial data allowance can choose one of Horizon eSIM’s fixed data plans. For instance, the Saint Lucia 20 GB 30 Days plan gives 20 GB of high‑speed data for 30 days, and the Caribbean 10 GB 30 Days plan offers 10 GB for the same duration. These fixed plans can be more economical than purchasing larger amounts of data if the user’s consumption is moderate, though they do not provide unlimited 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 has nine single‑country plans available for Saint Lucia, and it also offers fourteen multi‑country plans that include Saint Lucia among their coverage. The plans cost between about $5.81 and $309.44, with data caps ranging from 1 GB up to 20 GB; some of the plans also allow tethering.
