yaySIM eSIM Data Plans for Thailand

No, yaySIM does not currently provide an unlimited data eSIM for Thailand. All of the available plans list a specific data cap of 50GB and a set validity period.

Users who need a larger data allowance can choose from several fixed‑data options. For example, the TH_50_10 plan gives 50GB for 10 days, the TH_50_30 plan offers 50GB for 30 days, and the TH_50_180 plan provides 50GB for 180 days, all available at the same price. These fixed data plans can be more cost‑effective for most travelers unless they anticipate exceptionally high data usage.

yaySIM does not provide a Thailand eSIM that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for Thailand from this provider. Travelers can still use popular Voice over IP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific VoIP services, so users should verify that the apps they rely on are accessible in Thailand before purchasing.

yaySIM provides 22 single‑country data plans and 82 multi‑country plans for Thailand. The available plans span a price range from about $2.18 to $132.68 and a data cap range from 102 MB up to 50 GB, with validity periods that can be as short as one day or extend to a full year. The single‑country offerings typically give a fixed data amount for the duration of the plan, while the multi‑country options may include daily data caps that reset each day, allowing travelers to use the same data allowance across several destinations.
