eSimfly eSIM Data Plans for Thailand

eSimfly does not provide a truly unlimited data eSIM for Thailand. The plans that carry “Unlimited” in their name actually offer a fixed allowance of high‑speed data each day—either 1GB per day or 3GB per day—and after that limit the network speed is throttled, although the exact reduced speed is not listed.

Travelers who need larger amounts of data can choose from eSimfly’s fixed‑data plans instead. For example, a Thailand 50 GB 10‑day plan is available for $15.58 USD, while an Asia 100 GB 180‑day plan can be purchased for $257.40 USD, giving the user a larger, predictable data supply without the daily cap.

eSimfly does not provide any Thailand eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available from the provider. Travelers can still use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice‑call and messaging purposes.

eSimfly currently offers 16 single‑country data plans for Thailand and 97 multi‑country plans that include Thailand. The available plans range in price from approximately $1.23 to $257.40 and provide data caps that vary between 1 GB and 100 GB, with validity periods spanning from 1 day up to 365 days. The single‑country options include both fixed‑data plans, such as 5 GB for 30 days, and daily‑data‑cap plans that allow consumption to reset each day. The multi‑country selections follow a similar structure, offering a mix of fixed and daily‑cap models to accommodate different travel needs.
