SimBalkan eSIM Data Plans for Thailand

There is no truly unlimited high‑speed data eSIM for Thailand offered by SimBalkan. The plans that bear the word “Unlimited” actually provide 5GB of 5G data each day of the validity period, after which the speed is throttled to 1000 kbps. This means the data is limited, not unlimited.

Travelers who need more high‑speed data can opt for one of SimBalkan’s fixed data plans. For example, a 50GB bundle valid for 10 days costs $10.42 USD, and a 30GB bundle valid for 30 days costs $20.84 USD. These options give larger data allowances while maintaining 5G coverage and can be more cost‑effective for most users.

SimBalkan does not provide a phone number or SMS capability for Thailand. Travelers can only purchase data‑only eSIM plans from SimBalkan for use in Thailand. The available plans allow mobile data but do not support inbound or outbound calls or SMS. However, over‑the‑top communication apps such as WhatsApp, Telegram, and iMessage can generally be used over the data connection for voice and messaging. Some destinations may block or restrict access to specific VoIP services, so travelers should confirm that the apps they rely on are accessible in Thailand before purchasing a plan.

SimBalkan provides 11 single‑country plans for Thailand and 5 multi‑country plans that include Thailand in their coverage. The plans cover a price range of $5.58 to $51.14 and data caps from 1 GB up to 50 GB, with validity periods varying from 3 days to 180 days. Among the plans, 6 feature a daily data cap—where the allocated data resets each day—while 10 offer a fixed data amount, delivering the same total data over the entire validity period.
