Roamless eSIM Data Plans for Thailand

Roamless does not provide an unlimited data eSIM for Thailand. The available Thailand‑specific plans are fixed data bundles that range from 50GB to 200GB, all of which are 5G‑enabled. Some of these bundles are Pay‑as‑you‑go credits that do not expire, while others are fixed‑validity plans that last 30 days from activation.

If a traveler needs a large amount of data, the 200GB, 150GB, or 100GB Pay‑as‑you‑go options give the most coverage, and the 50GB 30‑day plan offers a lower‑cost alternative. Fixed data plans can be more cost‑effective for most users, but heavy data consumers may prefer the flexibility of the Pay‑as‑you‑go credit, which can be topped up as needed.

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.
