Merdata offers a total of fifteen different eSIM plans for Saint Lucia, split into eight single‑country options and seven multi‑country tours that include Saint Lucia.
The plans cover data caps between 500 MB and 10 GB, with validity periods ranging from one to thirty days, and prices from roughly $9.23 to $93.19.
Most of the plans feature a fixed data allocation that is delivered over the specified validity window; a few options include a daily data cap, limiting the amount that can be used each day. Both types are available across the single‑country and multi‑country selections, so travelers who need a relative short‑term amount of data or a daily pacing can find a plan that matches.
