Manet Travel does not provide an unlimited data eSIM plan for Sri Lanka. The available plans are fixed‑data bundles that expire after 30 days, with data caps of 3GB, 5GB, 10GB, 20GB, or 50GB. Travelers who need more data can purchase one of these larger bundles, such as the 50GB 30‑day plan, which offers a higher data allowance but still has a hard cap. For most visitors the fixed‑data bundles give a clear picture of the cost per gigabyte, and although they are not unlimited, they can be more economical for moderate to heavy data use compared to a Pay‑as‑you‑go model.
