Yesim eSIM Data Plans for Thailand

Yesim provides unlimited data eSIM plans for Thailand with validity periods ranging from 1 day up to 80 days and prices from $3.49 USD to $231.29 USD. All of these plans are advertised as unlimited, but the provider notes that speeds may be throttled after heavy usage according to a fair‑usage policy.

Travelers who require assured high‑speed data should contact Yesim directly to confirm whether the fine‑print applies to their intended usage and the typical amount of data that remains at normal 5G speed.

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

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.
