ESIMFUN eSIM Data Plans for Southeast Asia

ESIMFUN does not provide a truly unlimited data eSIM for Southeast Asia. All of the plans listed under the “Unlimited” name have a fixed allowance of 100GB of high‑speed data; after that limit is reached the speed may be reduced, although the specific throttled rate is not disclosed. Travelers who need a large data allowance can choose from several fixed‑data options, such as a 5‑day plan for 100GB, a 7‑day plan for 100GB, or a 30‑day plan for 100GB, each priced between $15.58 and $46.18 USD. Selecting a fixed‑data plan is often more cost‑effective unless a user expects to exceed the 100GB cap.

ESIMFUN does not offer an eSIM plan for Southeast Asia that includes a phone number or SMS capability. All of its available plans are data‑only, providing high‑speed internet access for the specified validity period. Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without needing a local phone number.

The ESIMFUN provider offers two eSIM plans that cover Southeast Asian nations. The “( High Speed Daily)” plan is available for Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand and Vietnam, while the “for” plan covers Indonesia, Malaysia, Singapore, Thailand and Vietnam; this plan also extends coverage to many other regions, though those additional territories are outside Southeast Asia.
