eSIM4Travel eSIM Data Plans for Thailand

eSIM4Travel does not provide a truly unlimited data eSIM for Thailand. The plans that carry “Unlimited” in their name offer a fixed allowance of 3 GB per day; once the daily quota is used, the connection speed is reduced to 1000 kbps. These are fixed data plans rather than unlimited ones.

For travelers who need more data, the provider offers fixed data plans that include larger high‑speed allowances, such as a 50 GB plan for 30 days or a 20 GB plan for 30 days. These plans provide unthrottled high‑speed data for the entire validity period and may be more cost‑effective for users who require substantial data usage in Thailand.

eSIM4Travel does not provide any Thailand eSIM plans that include a phone number or SMS capability. All Thailand plans from this provider are data‑only. Travelers who need voice or text can use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may restrict these apps, so it is advisable to check that the services needed are accessible in Thailand before purchasing.

eSIM4Travel lists 16 single‑country plans and 25 multi‑country plans that are usable in Thailand, for a total of 41 distinct data plans. The single‑country offerings range from around $0.56 to $63.14 USD and provide between 500 MB and 50 GB of data, with validity periods from 1 to 30 days. The multi‑country plans cover broader regions and fall within the same price and data ranges.

Among these plans, 15 are structured as daily data caps—allowing a fixed amount of data each day—while 26 are fixed data caps, granting a set amount for the entire validity period. Both types may include features such as tethering and a reduced speed fallback of 1 Gbps.
