EtravelSIM eSIM Data Plans for Thailand

EtravelSIM does not offer a truly unlimited data eSIM for Thailand. Every plan that is available carries a fixed data cap – the largest cap listed is 100GB for a limited period. Plans that contain “Unlimited” in their names actually grant a set amount of high‑speed data and, once that allowance is reached, the speed is throttled to 128kbps, which means the data is not unlimited.

Travelers who need a generous amount of data can choose from the fixed‑data options. For instance, a 100GB plan that lasts 2 days costs about $10.75 USD, a 100GB plan that lasts 7 days costs about $19.99 USD, and a 4GB/day plan that lasts 15 days costs about $57.00 USD. These plans provide large data allowances and may be more cost‑effective for most users, though they do not provide uninterrupted unlimited high‑speed data for an extended period.

EtravelSIM does not provide a Thailand eSIM that includes a phone number or SMS capability. All of the Thailand packages sold by EtravelSIM are data‑only. Travelers who need to make calls or send texts can use data‑based services such as WhatsApp, Telegram, or iMessage, which work over the data connection.

EtravelSIM lists 10 single‑country data plans that cover Thailand, along with 10 multi‑country plans that include Thailand as part of a broader regional package. The single‑country plans offer a variety of data caps, ranging from 4 GB up to 100 GB, and are priced between $8.49 and $109.99. Validity periods vary from 2 days to 365 days. Among the Thailand‑specific options, a small subset—three plans—feature a daily data cap, while the majority, 17 plans, are fixed‑data‑cap plans that allocate a set amount of data for the entire validity period. This flexibility allows travelers to choose a plan that best matches their usage pattern and budget.
