eSIM4Travel eSIM Data Plans for Thailand

eSIM4Travel does not offer a genuinely unlimited high‑speed data plan for Thailand. All “Unlimited” options listed have a daily cap of 3 GB; once that limit is reached the speed drops to 1000 kbps. Although the plan name includes the word “Unlimited, ” it does not provide infinite high‑speed data.

Travelers who need a larger data allowance can choose fixed data plans. For example, a 50 GB plan for 30 days costs $39.69 USD, and a 20 GB plan for 30 days is available for $14.49 USD. These fixed‑data options give a higher total data amount without throttle, making them more economical for heavy users.

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.
