iRoamly eSIM Data Plans for Thailand

iRoamly does not provide a truly unlimited data eSIM for Thailand. All of its listed plans for Thailand carry a data cap of 500GB; the plans are named “Unlimited, ” but this refers only to the plan title and not to an unlimited data allowance. After the 500GB threshold, the speed may be reduced, though the exact reduced speed is not specified in the available information.

Travelers who need high‑speed data can select one of iRoamly’s fixed‑data options, such as a 500GB plan valid for 1 day at $3.00 USD or a 500GB plan valid for 30 days at $82.00 USD. These fixed plans may be more cost‑effective for most users unless the user is an extremely heavy data consumer.

iRoamly does not offer a Thailand eSIM that includes a local phone number or SMS capability. The provider’s Thailand plans are data‑only, so they provide high‑speed internet access without calling or texting services.

Without a local phone number, travelers can still use voice and messaging apps such as WhatsApp, Telegram, and iMessage over the data connection, allowing them to communicate in Thailand without needing a traditional text or calling plan.

iRoamly provides 81 single‑country data plans that cover Thailand and 190 multi‑country plans that include Thailand. The catalog contains both fixed‑data‑cap options and daily‑data‑cap offers, with prices ranging from free to about US $257 and data caps spanning roughly 500 MB to 500 GB.
