Sim Local eSIM Data Plans for Thailand

Sim Local does not offer a truly unlimited high‑speed data eSIM for Thailand. All plans listed under the “Unlimited” name provide a fixed daily allowance (5 GB/day or 10 GB/day) and, after that limit is reached, the speed is reduced rather than remaining unlimited.

Travelers who need a larger amount of data may choose one of Sim Local’s fixed‑data plans instead. Examples include the Thailand 20 GB for 30 days plan for $17.50 USD and the Orange Holiday World 100 GB for 31 days plan for $93.50 USD. These plans give a set amount of high‑speed data, after which any remaining usage would be throttled. Choosing a fixed data plan can be more cost‑effective unless the user requires constant, unlimited high‑speed connectivity.

Sim Local does not offer any Thailand eSIM plan that includes a phone number or SMS capability. All of its Thailand plans are data‑only, so travelers will not receive an active line for voice calls or text messages.

You can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps you rely on will work in Thailand before purchasing a Sim Local eSIM.

Sim Local provides a total of 22 data plans for Thailand, which are divided into 9 single‑country plans and 13 multi‑country plans. The plans vary in type, with fixed data amounts and daily data caps available. Prices generally fall between $5.25 and $93.50, while data caps range from 3 GB up to 100 GB, giving travelers a broad selection to suit their usage needs.
