Saily eSIM Data Plans for Thailand

Saily does not provide a truly unlimited high‑speed data eSIM for Thailand. The only plan that carries “UNLIMITED” in its name, Thailand UNLIMITED 15 days, actually allows 5GB of high‑speed data each day before the speed drops to 1024kbps. After the 5GB daily limit, the data remains capped and does not stay unlimited.

If a traveler needs a larger data allowance, Saily offers fixed data plans that may be more cost‑effective. For example, Thailand 20GB for 30 days costs $19.99, and Thailand 10GB for 30 days costs $10.99. For those who travel beyond Thailand, a 100GB plan for 180 days covering Thailand and 18 other countries is also available for $179.99. These plans provide substantial data without the speed reduction that follows the daily cap of the “UNLIMITED” plan.

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 offers a variety of data plans for Thailand, including 6 single-country plans and 11 plans that provide coverage in multiple countries. These plans range in price from approximately $2.99 to $179.99 and offer data allowances from 1GB up to 100GB. Saily also provides both fixed data cap plans, offering a specific amount of data for a set period, and one plan with a daily data cap. Some plans may experience reduced speeds after a certain data usage threshold.
