Roamless eSIM Data Plans for Thailand

Roamless does not provide an unlimited data eSIM plan for Thailand. The available options include a 200GB Pay‑as‑you‑go plan, a 150GB Pay‑as‑you‑go plan, a 100GB Pay‑as‑you‑go plan, and a 50GB fixed data plan that is valid for 30 days.

The Pay‑as‑you‑go plans give you a data credit that is consumed as you use data; the credit does not expire, so unused data remains available for future trips. The 50GB plan is a fixed bundle that must be used within 30 days or until it is fully consumed. Both types of plans support tethering and full‑speed 5G connectivity while in Thailand.

Roamless does not provide a Thailand eSIM with a phone number or SMS capability. Only data‑only eSIM plans are available from the provider. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but should verify that these apps are accessible in Thailand before purchasing an eSIM.

Roamless offers 6 single‑country data plans and 13 multi‑country data plans for Thailand, all of which are fixed‑data‑cap offerings. The plans range in price from free to about $490 and in data from roughly 500 MB to 200 GB, with no daily data cap. All plans have no expiry, so unused data can be carried over to future trips. In addition, Roamless sells 22 Pay‑as‑you‑go credit options that can be topped up in various sizes; the credit does not expire, so unused balance can be used later. The fixed‑data plans also allow tethering and are available to new users.
