eSimfly does not provide a truly unlimited data eSIM for Thailand. The plans that carry “Unlimited” in their name actually offer 3GB per day of high‑speed data, after which the speed is throttled to 1000 kbps.
Travelers who need more data can choose from eSimfly’s fixed data plans. For example, the Thailand 50GB 10Days plan gives 50GB of high‑speed data for ten days, and the Global 100GB 31Days plan offers 100GB for 31 days. These fixed plans can be more cost‑effective for users who expect to use a large amount of data.
