ETravelSim does not provide a truly unlimited data eSIM for Thailand. The plan listed under the name “Thailand eSIM (ZF) Unlimited – 7 days” actually offers 100 GB of high‑speed data and is marked as having an unlimited name only. After that allocation the speed would be throttled, but no plan in the provider’s catalog has a data cap listed as unlimited.
Instead, travelers can choose from several fixed‑data options. For example, a 100 GB plan is available for 7 days at $19.99 USD, an 80 GB plan for 10 days at $15.99 USD, a 50 GB plan for 10 days at $8.49 USD, or a 50 GB plan for 30 days at $80.99 USD. These plans provide a clear data limit and price point, which can be more cost effective for most users unless a very heavy data consumption is required.
