SimBalkan eSIM Data Plans for Thailand

SimBalkan does not provide a truly unlimited data eSIM for Thailand. The plans that carry the word “Unlimited” give 1GB of high‑speed data—either 1GB in total for a single day or 1GB per day for longer periods up to 30 days. After the allotted data is used, no separate throttled speed is listed, so the allowance is effectively capped.

Instead, SimBalkan offers several fixed‑data plans that might better meet a traveler’s needs. Examples include a 10GB plan valid for 30 days priced at $6.80 USD, a 20GB plan for 30 days at $10.26 USD, and a 50GB plan for 10 days at $11.42 USD. These options provide larger data allowances and can be more cost‑effective for users who consume more data than the 1GB per day limit.

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 lists 13 single‑country plans that apply exclusively to Thailand and 5 multi‑country plans that cover Thailand along with other destinations. The available plans span a price range from roughly $1.04 to $51.78, with data caps between 500 MB and 50 GB and validity periods from 1 to 180 days. Four of the offerings are daily‑data‑cap plans that reset each day, while the remaining options are fixed‑data‑cap plans that provide a set amount for the entire validity period.
