Sim Local eSIM Data Plans for Thailand

Sim Local does not provide a truly unlimited high‑speed data eSIM for travelers in Thailand. The plans labeled “Thailand Unlimited Data 7 days” and “Thailand Unlimited Data 15 days” each include a 10 GB/day limit, after which the speed is reduced to a lower rate that is not highlighted in the plan details.

Travelers who need more data can choose a larger fixed‑data option. For example, the “Thailand 50 GB” plan allows 50 GB of high‑speed data for 10 days, and the “Thailand 20 GB” plan provides 20 GB for a 30‑day period. These fixed‑data alternatives may be more cost‑effective for most users unless they require high‑volume, unlimited usage.

Sim Local does not provide an eSIM plan for Thailand that includes a local phone number or SMS capability. Their Thailand eSIMs are data‑only, so travelers can use VoIP apps such as WhatsApp, Telegram or iMessage over the data connection for calls and messaging.

Sim Local offers seven single‑country data plans for Thailand and five multi‑country plans that can be used in additional destinations. The plans vary in price from about $4.00 to $52.25 and in data cap from 500 MB to 50 GB, with validity periods between 1 and 31 days. Among the plans, two are structured as daily data cap options, giving a fixed amount of data per day, while the remaining ten use a fixed data‑cap model that allocates a set amount of data for the entire validity period. This range of options allows travelers to choose a plan that fits both their budget and data‑usage needs.
