Travelsim Asia eSIM Data Plans for Thailand

Travelsim Asia does not provide an unlimited data eSIM for Thailand. All available plans list a specific data cap, ranging from 20GB to 50GB.

The fixed‑data options include, for example, a 50GB plan valid for 10 days priced at $15.99 USD, a 50GB plan with 180‑day validity at $49.99 USD, and a 20GB plan valid for 30 days at $19.99 USD. These plans offer 5G connectivity in Thailand and allow tethering. For most travelers, a fixed data plan can be more cost‑effective than an unlimited alternative, unless the user requires extremely high data usage.

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.
