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 currently offers 35 single‑country plans that can be used strictly in Thailand and 48 multi‑country plans that include Thailand as one of the covered destinations. The plans are divided into fixed‑data‑cap plans, which provide a set amount of data for the entire validity period, and daily‑data‑cap plans, which allow a daily amount of data that can be accumulated over the plan’s duration. Prices range from $4.27 to $478.46 USD, while data caps vary from 1 GB to 100 GB, giving a broad range of options for travelers’ needs.
