Roamless does not provide a truly unlimited data eSIM plan for Sri Lanka. The plans that carry the “Unlimited” label give 3GB of high‑speed data each day and reduce to 1Mbps after that daily allowance is used. Once a day’s 3GB have been consumed, the plan automatically switches to this throttled speed until the next daily cycle starts.
Travelers who need a larger or continuous high‑speed allocation can choose a fixed data plan, such as the Sri Lanka Data Plan that offers 50GB for 30 days, or use Roamless Pay‑as‑You‑Go credits that give 100GB or 150GB of full‑speed data with no expiry. These options allow larger usage without daily limits, although the Pay‑as‑You‑Go credit is consumable on a per‑use basis and can be topped up when necessary.
