Yesim eSIM Data Plans for Thailand

Yesim offers Unlimited data eSIM plans for Thailand. The provider’s Thailand Unlimited plans run from 1 day to 30 days, with prices ranging from $3.66 USD for a 1‑day plan to $48.05 USD for a 30‑day plan. Each plan is available on 5G and includes tethering, but speeds may be throttled after the fair‑usage policy is triggered. Travelers who want to confirm the specifics of the fair‑usage policy, such as typical data allowance before throttling, should contact Yesim directly.

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.
