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 have a daily data cap of 5GB or 10GB; once the daily limit is reached the speed is reduced, so the data is not unlimited.

Travelers who need a larger data allowance can choose from Sim Local’s fixed data plans. For example, the Thailand 20 GB for 30 days plan offers a 20 GB bundle that can be used over a month, and the Orange Holiday World 100 GB plan gives 100 GB for 31 days. These fixed‑data options are often more cost‑effective for most users unless they expect to consume data at a very high rate.

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.
