Saily eSIM Data Plans for Thailand

Saily does not provide a true unlimited data eSIM for Thailand. All of its Thailand‑only “UNLIMITED” plans actually offer a capped amount of high‑speed data – for example, the Thailand UNLIMITED 10‑day plan gives 5 GB of high‑speed data per day and reduces speed to 1024 kbps afterward. Because of this cap, the plans are not truly unlimited.

Users who need a higher data allowance can consider Saily’s fixed‑data eSIMs. A Thailand‑only option is the 20 GB plan for 30 days priced at $19.99, while a broader world‑coverage plan is the Asia and Oceania 100 GB for 180 days at $179.99. These fixed‑data plans often give better value for heavy data users than the capped “UNLIMITED” alternatives.

Saily does not offer a Thailand eSIM plan that includes a phone number or SMS capability. The available packages from this provider are data‑only, so users will not be able to receive or send standard SMS messages or make voice calls to traditional phone numbers. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but no native phone number or SMS service is provided.

Saily provides 10 single‑country plans for Thailand and 12 multi‑country plans that include Thailand. The plans span a price range from about $2.99 to $179.99, data caps between 1 GB and 100 GB, and validity periods from 7 to 365 days. Some plans offer fixed data amounts while others apply a daily data cap.
