Ovosim eSIM Data Plans for Thailand

Ovosim does not provide a truly unlimited high‑speed data plan for travelers in Thailand. Plans that carry “Unlimited” in the name actually offer daily data caps – for example, Thailand Unlimited MAX delivers 5GB per day, and Thailand Unlimited STANDARD gives 3GB per day. After the daily limit is reached, the speed throttles to a lower level (the specific reduced speed is not listed). For users who need a larger allotment without daily caps, Ovosim offers fixed‑size plans such as the Thailand 50GB 10‑day plan or the Thailand 20GB 30‑day plan, which can be more cost‑effective for heavy data users.

Ovosim does not provide an eSIM for Thailand that includes a local phone number or SMS capability. The provider only offers data‑only eSIM plans in that country. Travelers can still communicate through internet‑based services such as WhatsApp, Telegram or iMessage, which work over the data connection supplied by the Ovosim plan.

Ovosim offers a range of plans that include Thailand, split into single‑country and multi‑country options. There are 41 single‑country plans that cover Thailand exclusively, and 52 multi‑country plans that include Thailand among other destinations. Plans can be either fixed data bundles or daily data‑cap plans; fixed data plans provide a predetermined amount of data for the validity period, while daily plans allocate a data cap that resets each day. Across all Thailand‑available plans, prices vary from about $4.04 to $115.74, and data caps range from 1 GB up to 51 GB depending on the chosen plan.
