VeloeSIM does not provide an unlimited data eSIM for Thailand. All of its Thailand‑specific plans are fixed‑data bundles that must be used within a set validity period. The largest availability is a 20GB bundle for 30 days, priced at $18.99 USD for Thailand only, as well as a 20GB bundle that covers Thailand plus additional countries, and a 10GB bundle for 30 days at $9.99 USD.
If a traveler requires more data, the alternative is to purchase additional fixed data plans or top up as needed. Fixed data plans can be more cost‑effective for most users, whereas an unlimited data plan would only be necessary for extremely heavy data consumers.
