Ohayu eSIM Data Plans for Thailand

Ohayu does not offer an unlimited data eSIM plan for Thailand. The available plans provide fixed data allowances such as a 50GB plan valid for 90 days at $42.49 USD and a 20GB plan for 30 days at $19.99 USD.

Because unlimited data is not available, travelers who need large data volumes may consider one of these fixed‑data options. Selecting a fixed plan can be more cost‑effective unless the user is an extremely heavy data consumer.

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.
