No, ETravelSim does not provide a truly unlimited data plan for Lithuania. The plans that carry the “Unlimited” name give 4GB of high‑speed data per day; once that daily limit is reached the speed throttles to 128 kbps, so the data is not unlimited in the sense of unmetered high‑speed usage.
For travelers who need larger data allowances, fixed‑data plans are available. Examples include the 50 GB 30‑day plan, which offers 50 GB of high‑speed data for 30 days, and the 4 GB/day plan that delivers 4 GB each day at full speed for the chosen validity period. These plans provide the full data allowance without the speed reduction that applies after the “unlimited” cap is reached.
