CloudOn eSIM eSIM Data Plans for Thailand

CloudOn eSIM does not provide a genuinely unlimited data eSIM for Thailand. All plans that carry the name “Unlimited” grant a daily data allowance such as 3 GB per day on the Thailand Unlimited – 30 days plan, after which the speed is throttled to 1000 kbps. Travelers who need a larger total data allowance can choose a fixed high‑data plan. For example, CloudOn eSIM offers a Thailand 20 GB plan for 30 days, a Thailand 50 GB plan for 30 days, and a Thailand 100 GB plan for 180 days. These fixed‑data plans may be more cost‑effective if heavy data usage is expected compared with the capped “Unlimited” options.

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 provides 12 single‑country data plans that are tailored for travelers in Thailand. In addition, there are 31 multi‑country plans that include Thai coverage as one of several destinations. The plans span a price range from roughly $3.49 to $126.99 and offer data caps between 500 MB and 100 GB. Among them, some plans use a fixed data cap that grants a single, cumulative data amount for the entire validity period, while others employ a daily data cap that resets each day within the chosen duration, allowing travelers a predictable daily allowance.
