ETravelSim does not provide a plan that offers truly unlimited high‑speed data for Thailand.
All of its Thailand eSIM options are capped, with the largest plan providing 100GB of data for 7 days. Plans that carry the label “Unlimited” in their name are still limited—once the 100GB threshold is reached the speed is reduced, though the exact throttled rate is not listed.
Travelers who need a large amount of data can choose from the fixed‑data options in the catalogue, such as the 80GB 10‑day plan at $15.99 USD and the 50GB 10‑day plan at $8.49 USD. These fixed‑data plans are often more cost‑effective for typical usage compared to plans that propose “unlimited” access but actually include a high‑speed cap.
