Roamic eSIM Data Plans for Thailand

Roamic does not provide a truly unlimited high‑speed data eSIM for Thailand. All plans marketed with an “Unlimited” name provide a fixed data allowance of 3 GB per day; once this limit is reached the speed is throttled (the specific throttled speed is not listed in the available data).

If you need more data or prefer a flat rate, Roamic offers fixed‑data plans such as 20 GB for 30 days at $17.45 USD or 50 GB for 180 days at $48.89 USD. These options can be more cost‑effective for users who consume large amounts of data.

Roamic does not offer any eSIM plans that include a phone number or SMS service for Thailand. All of Roamic’s Thailand plans are purely data‑only. Travelers who need to make calls or send messages can rely on VoIP applications such as WhatsApp, Telegram, and iMessage, which work over the data connection and do not require a traditional phone number.

Roamic provides five single‑country plans and three multi‑country plans for Thailand. The single‑country offerings cover a spectrum of 1 GB to 20 GB data, priced roughly between $10 and $100. The multi‑country bundles give travelers data ranging from about 5 GB to 20 GB, with prices that also fall in the $10 to $100 bracket. Some plans charge a fixed data amount for the entire validity period, while others cap the data daily, providing a more predictable usage pattern if you anticipate steady consumption over a longer trip.
