YeeSiM eSIM Data Plans for Thailand

YeeSiM does not sell an unlimited data eSIM for Thailand.
Instead, the company offers fixed‑data plans that give travelers a large amount of high‑speed data. For example, a 90GB plan is valid for 365 days and costs $193.00 USD, while a 50GB plan is available for 180 days at $73.00 USD. Choosing a fixed‑data plan can be more economical unless the traveler is an extremely heavy data user and requires truly unlimited data.

YeeSiM does not provide eSIM plans for Thailand that include a local phone number or SMS capability. All of YeeSiM’s Thailand eSIM offerings are data‑only, meaning they deliver high‑speed internet on the network without exposing a native phone number. Travelers who need to make voice calls or send text messages can instead use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a local phone number or SMS service.

YeeSiM offers 16 single‑country data plans for Thailand. The plans range from about $3 to $202 and provide data caps between 500 MB and 90 GB, with validity periods that can extend from 1 day to 365 days. Among the Thailand offerings, users can choose from daily data‑cap options that refresh every 24 hours as well as fixed data‑cap plans that supply a set amount of data for the entire validity period. No multi‑country plans are listed specifically for Thailand on the directory.
