eSIMCard eSIM Data Plans for Thailand

eSIMCard does not provide a truly unlimited data eSIM for Thailand. All plans that carry the name “Unlimited” actually give a fixed data allowance – for example 1GB per day on the standard package or 2GB per day on the “Unlimited Plus” variants – and after that limit the speed is throttled to 512kbps or 2000kbps.

If you need a larger continuous data supply, eSIMCard offers fixed‑data options such as the Orange 20GB, Orange 50GB, and Orange 100GB plans. These provide a set amount of high‑speed data with no additional throttling, and for very heavy data users a fixed‑data plan can be more cost‑effective than purchasing multiple short‑term “Unlimited” packages.

eSIMCard currently does not offer a Thailand eSIM that includes a local phone number or SMS capability. Only data‑only eSIMs are available for Thailand. Travelers who need voice or text can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that those services are accessible in Thailand before purchasing, as some destinations may block or limit specific apps.

eSIMCard lists 31 single‑country plans and 100 multi‑country plans for Thailand. Plan prices range from about $2.28 to $395.07, while data caps span from 1 GB to 100 GB. Some plans feature a fixed data amount distributed over the validity period, whereas others allow a daily data cap that resets each day, offering flexibility for different travel needs.
