Ovosim eSIM Data Plans for Thailand

Ovosim does not provide a truly unlimited data eSIM for Thailand. All of its plans that use the “Unlimited” name actually contain a fixed data allowance that ranges from 15GB to 150GB, depending on the chosen validity period. Once the set data limit is reached, the plan’s speed is typically throttled, although the specific throttled speed is not listed in the details available.

Travelers who need a large amount of data can choose from the higher‑cap options. For example, a 90GB plan valid for 31 days costs $57.59 USD, and a 150GB plan valid for the same period costs $77.16 USD. These fixed‑data plans are often a more cost‑effective solution for those who anticipate heavy use compared to options that advertise unlimited data yet are limited in practice.

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 32 single‑country plans for Thailand and 52 multi‑country plans that cover Thailand as part of a broader itinerary. The plans generally feature fixed data amounts rather than daily data caps. Prices range from roughly $5.18 to $115.19, data allowances span from 1 GB up to 150 GB, and validity periods vary between 6 and 31 days.
