MeSIM does not provide a truly unlimited data eSIM for Thailand. The plans that carry “unlimited” in their name are fixed‑data plans that offer a set amount of high‑speed data per day, after which the speed is throttled. For example, the Thailand 7‑day unlimited eSIM gives 15GB/day of high‑speed data before the speed drops to 1 Mbps, and the Thailand 10‑day unlimited eSIM offers 1GB/day of high‑speed data before the speed is reduced to 384 kbps. These fixed‑data plans can be more cost‑effective for most travelers, while extremely heavy data users may need to consider a higher‑cap plan or a pay‑as‑you‑go option.
