Ovosim eSIM Data Plans for Thailand

Ovosim does not provide a truly unlimited data eSIM for Thailand. All plans labeled “Unlimited” have a daily data cap—such as 2GB/day for the Thailand Unlimited LITE plan, 3GB/day for Thailand Unlimited STANDARD, and 5GB/day for Thailand Unlimited MAX—so high‑speed data stops once the daily limit is reached. After the limit, speed is reduced to a throttled rate that is not specified.

Instead, travellers can choose from fixed‑data plans that offer larger amounts of data. For example, the Thailand 50GB plan gives 51GB for 10 days, and the Thailand 20GB plan offers 20GB for 30 days, both without the daily capping mechanism. These fixed‑data options can be more cost‑effective for heavy data users than trying to work around the capped “Unlimited” plans.

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.
