Simology eSIM Data Plans for Thailand

Simology does not provide a true unlimited data eSIM for Thailand. The plans labeled “Unlimited” each offer 1GB per day at full speed and then reduce the speed to 1 Mbps after that daily limit is reached. Because a fixed data allowance is capped, the plans are not unlimited in the intended sense.

If a larger data allowance is desired, Simology offers fixed‑data plans. For example, the eSIM TH, 50 GB, 30 days plan costs $27.88 USD, the eSIM TH, 20 GB, 30 days plan costs $20.90 USD, and the eSIM TH, 10 GB, 30 days plan costs $12.77 USD. These plans provide a set amount of high‑speed data that must be used within the 30‑day validity period.

Simology does not provide a Thailand eSIM that includes a phone number or SMS capability. Travelers can purchase only a data‑only eSIM from Simology, and may use VoIP applications such as WhatsApp, Telegram, and iMessage for calls and texting over the data connection. Some destinations may block or restrict specific VoIP services, so travelers should verify the accessibility of the apps they rely on in Thailand before buying a plan.

Simology provides 13 single‑country data plans for Thailand and an equal number of multi‑country plans. The single‑country bundle covers Thailand alone, while the multi‑country options include Thailand with other destinations. Plans range from about $2.89 to $87.14 and offer data caps from 1 GB to 50 GB for validities between three and thirty days. Some plans are fixed‑data packages, giving a set amount of data that can be used over the entire validity, while others use a daily data cap that limits the amount of data you can consume each day.
