Ohayu eSIM Data Plans for Thailand

Ohayu does not offer any unlimited data eSIM plans for Thailand. Travelers who need data in Thailand can choose from a selection of fixed data plans. For example, the Thailand 50GB 90 days plan allows up to 50GB of high‑speed data for 90 days and costs $42.49 USD, while the Thailand 20GB 30 days plan provides 20GB of data for 30 days at $19.99 USD. Selecting a fixed data plan is generally more cost‑effective unless the user has an extremely high data consumption requirement.

Ohayu does not provide a Thailand eSIM that includes a phone number or SMS capability. The provider’s Thailand plans are data‑only, so travelers can use the mobile data for internet access but cannot make voice calls or send SMS directly through the eSIM. Instead, VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection for messaging and calling.

Ohayu offers six single‑country data plans and four multi‑country plans that cover Thailand. The available plans range from $5.99 to $49.49 and provide between 2 GB and 50 GB of data, with validity periods lasting from 15 to 90 days. Most plans use a fixed data amount, giving travelers a clear indication of how much data they will receive over the validity period. The multi‑country plans include Thailand in a broader coverage area, allowing seamless use across several destinations while keeping the same data allocation and pricing tier.
