Travelsim Asia eSIM Data Plans for Thailand

Travelsim Asia does not offer an unlimited data eSIM for Thailand. Their catalog consists of fixed‑data plans. For instance, a 50GB plan valid for 10 days is priced at $15.99, while a 20GB plan valid for 30 days costs $19.99. For travelers who need a longer period, the 50GB plan valid for 180 days is available at $49.99. Choosing a fixed data plan can be more cost‑effective unless the user is an extremely heavy data consumer.

Travelsim Asia does not provide eSIM plans for Thailand that come with a local phone number or SMS capability. The service only offers data‑only eSIMs for use in the country. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without a dedicated phone number.

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.
