CloudOn eSIM eSIM Data Plans for Thailand

CloudOn eSIM does not provide a truly unlimited data eSIM for Thailand. All plans that carry the word “Unlimited” in their name actually offer a daily data allowance of 3GB or 2GB; once that daily limit is reached the speed is throttled to 1000kbps.

For travelers who need more data without daily caps, CloudOn eSIM offers fixed‑data plans such as the Thailand 20 GB – 30 days plan, the Thailand 50 GB – 30 days plan, and the Asia 100 GB – 180 days plan. These plans give a set amount of high‑speed data for the entire validity period and can be more cost‑effective for heavy data users.

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.
