ESIMFUN eSIM Data Plans for Thailand

ESIMFUN does not provide a truly unlimited data eSIM for Thailand. All of its Thailand plans carry a high‑speed data cap of 100 GB, even when the plan name includes the word “Unlimited.” After the 100 GB allowance, the plan stops offering high‑speed data, but the dataset does not specify a reduced speed.

Travelers can choose from fixed‑data options such as the 100 GB plan valid for 30 days at $43.89 USD or the 100 GB 15‑day plan at $32.91 USD. These plans are the most generous short‑term options available from ESIMFUN and may be more cost‑effective for most users than any hypothetical unlimited plan.

ESIMFUN does not provide Thailand eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for Thailand. Users can still communicate through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

ESIMFUN lists 54 data plans for Thailand, comprising one single‑country offering and 53 multi‑country options. The plans range from about $8.12 to just over $207, with data allocations between 1 GB and 100 GB. Among these, 39 plans provide a fixed amount of data while 15 cap the daily usage, giving travelers flexibility depending on their travel itinerary.
