SeferESIM does not provide a true unlimited data eSIM plan for Thailand. The plans labeled as “Unlimited” in the provider’s marketing actually limit high‑speed data to 1 GB per day; after that limit the speed is throttled to 1000 kbps. Travelers who need more data without speed reduction can choose from SeferESIM’s fixed data plans, such as the 50 GB bundles available for 10 days, 30 days, or 180 days. These fixed plans provide a larger data allowance—up to 50 GB—for a set validity period and remain high‑speed throughout the entire validity, offering a more cost‑effective option unless a traveller’s usage exceeds the 1 GB/day threshold.
