Astaroam does not provide a truly unlimited data eSIM for Thailand. The plans listed under the “Unlimited” label all include a fixed daily data allowance, such as 5GB/day or 3GB/day, and cap the speed to 1000kbps after the daily amount is used. After the allotted data for the validity period is exhausted, the remaining period continues to be usable but with the reduced speed.
For travelers who need larger amounts of high‑speed data without a daily cap, Astaroam offers fixed data plans such as the 20 GB plan valid for 30 days or the 50 GB plan valid for 90 days. These plans provide a single, larger data allowance that can be used at normal speeds throughout the validity period. Choosing a fixed data plan can be more cost‑effective for most users unless they expect to consume data beyond the daily limits of the “Unlimited” plans.
