ESIMFUN eSIM Data Plans for Southeast Asia

ESIMFUN does not provide truly unlimited data eSIM plans for Southeast Asia. All listed plans are titled “Unlimited” but include a fixed data cap of 100GB for the validity period. After the 100GB is consumed, the high‑speed data is reduced (the reduced speed is not specified in the data). Fixed‑data plans, such as the 100GB plan valid for 15 days or the 100GB plan valid for 30 days, are available as alternatives. Choosing a fixed‑data plan can be more cost‑effective for most travelers unless the user requires very high data usage beyond the 100GB allowance.

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.

ESIMFUN offers two eSIM plans that cover Southeast Asian countries: the first plan, labeled with a hyphen, includes Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam, while the second plan, named “for”, includes Indonesia, Malaysia, Singapore, Thailand, and Vietnam.
