Sim Local eSIM Data Plans for Thailand

Sim Local does not offer a truly unlimited data eSIM for Thailand. The plans that carry the words “Unlimited” in their name, Thailand Unlimited Data 7 Days or Thailand Unlimited Data 15 Days, actually provide a daily high‑speed data allowance of 10 GB; after that amount the network speed may be reduced.

Travelers who need more data can choose from fixed‑data plans instead. For example, Thailand 50 GB delivers 50 GB of high‑speed data valid for 10 days, Thailand 20 GB offers 20 GB for 30 days, and Thailand 10 GB provides 10 GB for 30 days. These alternatives can be more cost‑effective for heavy data users or longer stays.

Sim Local does not offer Thailand eSIM plans that include a local phone number or SMS capability; only data‑only packages are available. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the eSIM data connection for voice and messaging.

Sim Local offers a total of 10 distinct data packages in Thailand. These include seven single‑country plans that give you access only to Thai networks, and three multi‑country plans that provide connectivity in Thailand as well as other destinations. Prices for these packages range from $6.75 for the smallest 1 GB plans up to $52.25 for the largest 50 GB options, with validity periods between one and thirty‑one days. Some of the packages cap data on a daily basis while others provide a fixed data allowance, allowing travelers to choose based on their usage patterns.
