ETravelSim does not provide a truly unlimited data eSIM for Sri Lanka. The plans listed as “Unlimited” actually give 4 GB per day; once that daily quota is reached the speed is reduced to 128 kbps. That means no continuous high‑speed data without limits.
If a traveler wants higher data capacity without the daily throttle, ETravelSim offers several fixed‑data options. For example, a 20 GB plan for 30 days costs $17.99, a 25 GB plan for 30 days costs $45.99, and a 50 GB plan for 30 days costs $80.99. These fixed plans provide full‑speed data throughout their validity and may be more cost‑effective for most users unless an extremely high daily consumption is required.
