Sim Local eSIM Data Plans for Thailand

Sim Local does not provide a truly unlimited data eSIM for Thailand. The plans that carry “Unlimited” in their name actually give a daily data allowance of 10GB/day or 5GB/day; once that daily limit is reached the speed is reduced, so the data is not unlimited.

Travelers who need a larger, fixed amount of high‑speed data can choose from Sim Local’s fixed data plans. Examples include the Thailand 20GB for 30 days plan, the Orange Holiday World 100GB plan valid for 31 days, and the Orange Holiday World 50GB plan also valid for 31 days. These fixed data plans offer a set amount of high‑speed data for a specified validity period and can be more cost‑effective for most users unless they are extremely heavy data consumers.

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 offers 9 single‑country plans and 15 multi‑country plans for Thailand.
The available plans vary in price from about $4.75 to $93.50 and provide data caps ranging from 1 GB to 100 GB, with validity periods between 3 and 31 days. Some of the plans feature a fixed data allotment, while others provide a daily data cap to better suit short‑term usage.
