ESIMFUN eSIM Data Plans for Southeast Asia

ESIMFUN does not provide a truly unlimited high‑speed data plan for Southeast Asia. All of the options are labeled “Unlimited” but each includes a 100GB data cap. After the 100GB is reached the plan no longer guarantees unrestricted high‑speed connectivity; the dataset does not specify a reduced speed, so travelers will experience a speed drop once the cap is hit.

If a user prefers a fixed‑data plan instead, ESIMFUN offers several alternatives with large data allowances. For example, a 5‑day plan provides 100GB for $15.61 USD, while a 30‑day plan gives 100GB for $46.24 USD. These fixed‑data options may be more cost effective for travelers who need to browse, stream, or work without exceeding a set limit.

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 “High Speed Daily” plan covers Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. The “for” plan includes Indonesia, Malaysia, Singapore, Thailand, and Vietnam as its Southeast Asian coverage and also offers service in many additional countries but those are outside the region in question. The “Subscription - every” plan reaches Indonesia, Cambodia, Myanmar, Malaysia, Philippines, Singapore, Thailand, and Vietnam.
