Cellesim eSIM Data Plans for Thailand

Cellesim does not provide an unlimited data eSIM for Thailand. The available options are fixed data plans that come with a set data allowance and a defined validity period. For example, Cellesim offers a 50GB plan valid for 30 days at $64.58 USD, a 50GB plan valid for 180 days at $112.00 USD, a 20GB plan valid for 30 days at $28.70 USD, a 10GB plan valid for 30 days at $15.30 USD, and a 5GB plan valid for 30 days at $9.45 USD.

Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from an unlimited plan.

Cellesim does not provide a Thailand eSIM plan with a local phone number or SMS capability. Only data‑only eSIMs are available. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but some destinations may restrict or block these services, so it is advisable to verify that the apps you need remain accessible in Thailand before purchasing.

Cellesim offers 18 single‑country data plans for Thailand, with no multi‑country bundles available. The plans span a price range from $2.45 to $180 and a data range from 1 GB to 50 GB. Among these, 10 plans have a daily data cap, meaning the allocated data resets each day, while 8 plans are fixed‑data caps that remain constant for the entire validity period.
