nextSIM eSIM Data Plans for Thailand

nextSIM offers 31 single‑country data plans for Thailand and 18 multi‑country plans. The plans range in price from about $1.62 to $1,289.41 and provide data between 1 GB and 50 GB, with validity periods from 1 day up to 30 days. Daily data‑cap options are available for 12 plans, while fixed‑data cap options cover 37 plans, giving users flexibility between a set amount of data and a daily data limit.

No, nextSIM does not provide a true unlimited data eSIM for Thailand. All plans labeled “Unlimited” actually include a fixed amount of high‑speed data—either 1GB or 2GB per day—after which the speed is reduced to either 512kbps or 2000kbps. While these plans give the impression of unlimited usage, the data cap limits the amount of unthrottled high‑speed data that can be consumed.

Travelers who need more data can select from a range of fixed‑data packages. For example, the eSIM Thailand 50GB 30Days Economy plan offers 50GB of high‑speed data for 30 days, while the eSIM Thailand 20GB 30Days Economy provides 20GB for the same period. These fixed‑data plans can be more cost‑effective for most users and avoid the speed reductions that come with the “Unlimited” options.
