Saily eSIM Data Plans for Thailand

Saily does not provide a truly unlimited data eSIM for Thailand. The plans that carry the name “UNLIMITED” are actually capped at 5 GB per day; once the daily quota is reached the speed is throttled to 1024 kbps or, in some cases, to 1 kbps. Travelers who need uninterrupted high‑speed data may find it more economical to choose one of Saily’s fixed‑data plans, such as the 20 GB plan that is valid for 30 days.

Saily does not provide a Thailand eSIM that includes a local phone number or SMS capability. The only plans available for Thailand from Saily are data‑only. Travelers can still use voice and messaging applications such as WhatsApp, Telegram, or iMessage over the data connection, but no traditional phone number or SMS service is offered.

Saily provides 12 single‑country plans and 22 multi‑country plans in Thailand. The offerings span a price range from about $2.99 to $159.99 and a data cap range of 1 GB to 30 GB, with validity periods between 5 and 365 days. Some plans feature a daily data cap, which limits the amount of data you can use each day, while the fixed data cap plans allow you to consume the full data allowance at any time during the validity period. This gives travelers a variety of options to match both short‑term and extended stays.
