PRIeSIM eSIM Data Plans for Thailand

PRIeSIM does not provide a truly unlimited high‑speed data eSIM for Thailand.
The plans that carry the “Unlimited” name in their title include a capped amount of data each day—5GB/day for the Thailand Unlimited 3/5/7‑day plans and 3GB/day for the Asia Unlimited 3‑ to 30‑day plans. Once the daily data allowance is reached, the speed is reduced. No plan in the catalogue lists an unlimited data cap.

For travelers who want a large amount of high‑speed data, PRIeSIM offers fixed‑data bundles that are suitable alternatives. Examples include the Thailand 20GB plan for 30 days and the Asia 100GB plan for 180 days. These fixed‑data plans provide a substantial data allowance within a set validity period and can be more cost‑effective for most users.

PRIeSIM does not provide a Thailand eSIM that includes a local phone number or SMS capability. The provider offers only data‑only plans for Thailand. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Thailand before purchasing.

PRIeSIM offers 10 single‑country data plans that cover Thailand and 28 multi‑country plans that include Thailand. The available plans span a price range from $1.71 to $236.61 and a data cap range from 200 MB to 100 GB. Among the plans, 9 are structured with a daily data cap while 29 are fixed‑data‑cap plans, and several of them allow tethering.
