No, aloSIM does not provide an unlimited data eSIM plan for Sri Lanka. The available plans for Sri Lanka are fixed data bundles with caps of 10 GB, 20 GB, or larger amounts such as 50 GB or 100 GB that are valid for 30, 90, or 180 days. Travelers who need more data can choose one of these fixed plans, which may be more cost‑effective than a pay‑as‑you‑go option unless they are extremely heavy data users.
