Ohayu eSIM Data Plans for Thailand

Ohayu offers unlimited‑data eSIM plans for Thailand that cover 5, 10, 15, and 30 days. The prices range from $14.99 USD for the 5‑day plan to $43.99 USD for the 30‑day plan, and each plan provides data for the stated validity period. The maximum listed speed is 1000 kbps, and the provider notes that speeds may be throttled after heavy usage under a Fair Usage Policy. Travelers who want to confirm whether the Fair Usage Policy applies and how much data remains at normal speed should contact Ohayu directly.

Ohayu does not offer an eSIM plan for Thailand that provides a phone number or SMS capability. The provider only offers data‑only plans in this destination. Travelers who need voice or text messaging can use 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 the eSIM.

Ohayu offers ten single‑country data plans for Thailand and an additional four multi‑country plans that include Thailand among other destinations. The single‑country options range in price from $4.99 to $29.99 and provide data caps between 2 GB and 10 GB, with validity periods from 5 to 30 days; the multi‑country plans are priced between $14.99 and $49.49, offering larger data allowances up to Unlimited and validity periods extending up to 90 days. Tethering is allowed across all plans, though speeds may be throttled with a nominal limit of 1000 kB/s.
