eSIMCard eSIM Data Plans for Thailand

eSIMCard does not provide a truly unlimited high‑speed data plan for Thailand. The plans that carry the “Unlimited” label all have a fixed data cap, such as 1GB or 2GB per day, and after the cap is reached the speed is reduced to 500kbps, 512kbps, or 2000kbps. For travelers needing large amounts of high‑speed data, eSIMCard offers fixed‑data alternatives such as a 100GB plan valid for 180 days or a 50GB plan for 90 days, which deliver unthrottled speeds throughout their validity. Choosing a fixed‑data plan can be more cost‑effective for users who expect to use substantial data while staying in Thailand.

eSIMCard does not provide eSIM plans that include a phone number or SMS for travelers in Thailand. The provider only offers data‑only plans in this destination. If a traveler wishes to make calls or send messages, popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection, eliminating the need for a local phone number or text messaging capability.

eSIMCard’s catalogue for Thailand includes 35 single‑country plans and 47 multi‑country plans. The single‑country offers are generally fixed data caps ranging from 1 GB up to 100 GB, with prices spanning approximately $4.27 to $478.46 USD and validity periods of 1 to 365 days. The multi‑country options are similar in scope but provide access to several destinations beyond Thailand while retaining the same price and data ranges. Some plans feature daily data cap limits, allowing users to reset their data allowance each day, whereas most are fixed‑data‑cap plans that retain a single, cumulative data allowance for the entire validity period. This broader spectrum gives travelers flexibility depending on whether they need a short‑term burst of data or a longer‑term, consistent data requirement across multiple countries.
