Simbye does not offer a truly unlimited data eSIM for Thailand. All of its plans for Thailand have a hard data cap, after which the speed is throttled. For example, the “Thailand Unlimited 7 Days with Real Thai Phone Number on DTAC 5G” gives 50 GB of high‑speed 5G data before reducing the speed to 1 Mbps. Other similar plans provide 2 GB per day for the stated validity period, also with a reduced speed after the limit is reached. These fixed‑data plans can be a cost‑effective choice for most travelers unless they need unlimited high‑speed data.
