CloudOn eSIM eSIM Data Plans for Thailand

CloudOn eSIM does not provide a true unlimited data eSIM plan for Thailand.
All plans listed for Thailand have a hard data cap, such as 20 GB for 30 days, 50 GB for 30 days, or 100 GB for 180 days. Fixed‑data plans can offer large data allowances and are usually more cost‑effective than paying for high‑speed data that throttles after a certain daily limit, which is what the “Unlimited”‑named plans actually provide.

CloudOn eSIM does not offer a Thailand eSIM that includes a local phone number or SMS capability. Only data‑only plans are available for travelers going to Thailand. Users who need voice or messaging can rely on VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that these services are accessible in Thailand before purchasing, as some destinations may block or restrict specific apps or VoIP services.

CloudOn eSIM offers 21 single‑country plans and 34 multi‑country plans that cover Thailand. The available plans range from about $3.49 up to $99.99, with data caps spanning from 500 MB to 100 GB and validity periods from 3 to 180 days. The single‑country plans provide data usage limited to Thailand alone, while the multi‑country plans allow data to be used in several countries (including Thailand) as part of a broader coverage package. In addition, CloudOn provides both fixed‑data‑cap options and daily‑data‑cap options—fixed plans keep the same data amount for the entire validity, whereas daily plans reset the data allowance each day.
