Yesim eSIM Data Plans for Thailand

Yesim offers a range of unlimited data eSIM plans that cover Thailand. The plans are available with validity periods from 1 day up to 80 days, and prices vary accordingly, starting at $3.60 USD for a 1‑day plan and going up to $223.91 USD for an 80‑day pass.

Although the data cap is listed as unlimited, the plans are subject to a Fair Usage Policy. After heavy usage, speeds may be reduced or throttled, and users who are concerned about potential speed restrictions should contact Yesim directly to confirm the specific limits and typical speed thresholds that apply.

Yesim does not provide a Thailand eSIM that includes a phone number or SMS. All Thailand eSIMs offered by Yesim are data‑only plans. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but availability of these services can vary by region; visitors should confirm that the apps they rely on are accessible in Thailand before purchasing.

Yesim provides a range of data plans for Thailand that are divided into single‑country and multi‑country options. For travelers focused solely on Thailand, there are 11 single‑country plans that deliver data from a modest 500 MB up to unlimited data. Those who plan to visit multiple countries and want Thailand included can choose from 35 multi‑country plans; these also span the same data spectrum, from 500 MB to unlimited, but add the flexibility to roam across a broader network of destinations. The price range across all these plans varies from as little as $0.52 to $231.29, with the largest plans offering the most generous data caps. Plans may differ in how data is allocated—some provide a fixed data amount for the entire validity period, while others impose a daily data cap. Tethering is typically allowed, and as with many travel eSIMs, speed may be throttled after a certain threshold.
