Horizon eSIM eSIM Data Plans for Saint Lucia

Horizon eSIM does not provide an unlimited data eSIM for Saint Lucia.
The provider’s available plans for the island are fixed‑data bundles. For example, the Saint Lucia 20GB 30Days plan offers 20 GB of data for 30 days, and the Caribbean 10 GB 30days plan gives 10 GB for 30 days. These fixed data plans can be more cost‑effective than a generic unlimited offering for travelers who do not need extra data beyond the allotted amount.

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.
