merdata eSIM Data Plans for Thailand

Merdata does not provide an unlimited data eSIM for Thailand. Travelers can choose from several fixed‑data plans instead, such as the eSIM Thailand 50‑GB plan valid for 10 days, priced at $18.90 USD, or the 50‑GB plan valid for 180 days, priced at $63.24 USD. A 20‑GB plan for 30 days is also available for $21.01 USD.

For most visitors a fixed‑data plan is a cost‑effective choice unless they expect to use an extremely high volume of data. The fixed plans offer a clear data allowance that can be matched to travel needs, and because there is no data cap, users avoid the risk of throttling or extra charges that can accompany unlimited‑type offerings.

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.
