Saily eSIM Data Plans for Thailand

Saily does not provide a true unlimited data plan for Thailand. Their “UNLIMITED” plans supply 5 GB per day; once that daily amount is reached the speed drops to 1 kbps or 1000 kbps, depending on the specific package.

If a user needs a fixed data allowance, Saily offers several alternatives. For example, the Thailand 20 GB 30 days plan costs $19.99 USD, and the Thailand 25 GB 60 days plan costs $48.99 USD. These fixed‑data options may be more cost‑effective unless the traveler requires very high daily data consumption.

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.
