Travelsim Asia eSIM Data Plans for Thailand

Travelsim Asia does not provide an unlimited data eSIM for Thailand. The available plans for Thailand are fixed data bundles, such as a 50GB plan valid for 10 days, a 50GB plan valid for 180 days, and a 20GB plan valid for 30 days.

Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user expects to consume data at a very high rate that would exceed the bundle’s allowance.

Travelsim Asia does not offer a Thailand eSIM plan that includes a phone number or SMS capability; only data‑only eSIM options are available for Thailand.

Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may block or restrict these services. It is advisable to verify that the apps you rely on work in Thailand before purchasing a plan.

Travelsim Asia lists 7 single‑country plans that are specifically available for Thailand, and it also offers 14 multi‑country plans that include Thailand as one of the covered destinations.
The plans cover a data cap ranging from 1 GB up to 50 GB and are priced between about $1.99 and $120.99. Most of the plans provide a fixed amount of data that can be used over their validity period, and some also allow tethering to other devices.
