Saily eSIM Data Plans for Thailand

Saily does not provide a truly unlimited data eSIM for Thailand. All plans that include “UNLIMITED” in the name actually offer 5 GB per day and throttle the speed once that daily amount is reached. If a traveler needs higher or continuous data, Saily offers fixed data plans such as the Thailand 20 GB 30 days plan, which gives 20 GB for 30 days, or larger caps like the Thailand UNLIMITED 5 days plan that delivers 5 GB each day for five days before the speed drops. Choosing a fixed data plan can be more cost‑effective than buying a high‑daily‑cap “unlimited” plan unless the user is an extremely heavy data consumer.

Saily does not provide any Thailand eSIM plans that include a local phone number or SMS capability. The available plans are data‑only; travelers can use the internet connection to access VoIP applications such as WhatsApp, Telegram or iMessage for voice and text communication. However, some destinations may restrict access to specific apps or VoIP services, so it is advisable to confirm that the applications you rely on will be accessible in Thailand before purchasing a plan.

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.
