GulfData does not provide a truly unlimited data eSIM for Thailand. The plans that carry the “Unlimited” name actually give 1GB per day at full speed, after which the speed is reduced to 512 kbps.
Travelers who need a larger, unrestricted data allowance can choose one of GulfData’s fixed data plans, such as the Thailand 50GB plan valid for 180 days or the Thailand 20GB plan valid for 30 days. These plans offer a fixed amount of high‑speed data without the speed throttling that follows the daily 1GB limit.
