eSimpli eSIM Data Plans for Thailand

eSimpli does not provide a truly unlimited data eSIM for Thailand. The plans that carry the word “Unlimited” in their name only supply 1 GB per day of high‑speed data, after which the speed is reduced to 1250 kbps.
For travellers who need a larger, uncapped data allowance, eSimpli offers fixed data plans such as a 50 GB for 30 days plan or a 20 GB for 30 days plan. These plans give a set amount of high‑speed data without a daily throttle and can be more cost‑effective for regular or heavy usage.

eSimpli does not provide Thailand eSIMs that include a phone number or SMS capability. Only data‑only plans are available from this provider for the Thai destination. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Thailand before purchasing a plan.

eSimpli lists 9 single‑country plans and 13 multi‑country plans for Thailand, a total of 22 data plans. The plans vary from $5.65 to $108.47 and provide data caps ranging from 1 GB up to 50 GB, with validity periods between 5 and 30 days. Among these, 7 plans feature a daily data cap limiting usage each day, while 15 offer a fixed data cap that allows the full amount to be used over the entire validity. This provides travelers with a range of options based on budget, data needs and the length of their stay.
