merdata eSIM Data Plans for Thailand

merdata does not offer an unlimited data eSIM for Thailand. Travelers who need high‑speed internet in Thailand can choose from several fixed‑data plans instead, such as the eSIM Thailand 50GB 10 days plan priced at $18.58 USD and the eSIM Thailand 50GB 180 days plan priced at $62.17 USD. For those who also want coverage in neighboring countries, the eSIM Southeast Asia (7 countries) 50GB 180 days plan is available for $82.92 USD. Selecting a fixed‑data plan can be more economical unless a user is an extremely heavy data consumer who would benefit from an unlimited option.

Merdata does not provide a Thailand eSIM plan that includes a phone number or SMS capability. All of its available Thailand eSIMs are data‑only, so you will not receive a local number for voice or text services from the provider.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but those services may be restricted in Thailand. It is advisable to confirm that the apps you rely on are accessible in the destination before purchasing an eSIM.

merdata provides 14 single‑country data plans and 58 multi‑country plans that include Thailand. The single‑country offerings give travelers a variety of data amounts that can be bought for a set period, ranging from 500 MB to 50 GB, with prices between roughly $0.92 and $102.12. The multi‑country plans are designed for travelers who may visit several destinations in one trip; they also cover a similar data spectrum and price range, although the specific data caps and validity periods differ from plan to plan, with some plans featuring a fixed data bundle while others apply a daily data cap.
