eSimfly eSIM Data Plans for Southeast Asia

eSimfly does not provide a truly unlimited data eSIM for Southeast Asia. All plans marketed under the “Asia Unlimited” name give only 1 GB of high‑speed data per day (or 1 GB total for one‑day plans) and then the speed is reduced once the cap is reached. For travelers who need larger data allowances, eSimfly offers fixed‑data plans such as the 100 GB 180‑day plan, the 90 GB 365‑day plan, and the 60 GB 365‑day plan. These plans give a fixed amount of high‑speed data for the entire validity period and can be more cost‑effective for users who consume a lot of data.

eSimfly does not offer any Southeast Asia eSIM plan that includes a phone number or SMS capability. All available eSIMs from this provider are data‑only plans. Travelers can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection to make calls and send messages without needing a phone number or SMS service.

The eSimfly eSIM plans that cover countries in Southeast Asia include Indonesia, Malaysia, Singapore, Thailand, Vietnam, Cambodia, Laos, the Philippines, Brunei, and Timor‑Leste. Several plan names provide this regional coverage: the Asia (7 areas) plan lists Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam; the Asia (12 areas) plan lists Indonesia, Cambodia, Malaysia, Singapore, Thailand, and Vietnam; the Asia (20 areas) plan lists Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam; the Asia‑20 plan lists Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam; Discover Global lists Brunei, Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Timor‑Leste, and Vietnam; Asia Unlimited lists Indonesia, Malaysia, Singapore, Thailand, and Vietnam; and the simpler Asia plan lists Indonesia, Malaysia, Singapore, Thailand, and Vietnam. Some of these plans, such as the Asia or Asia‑20 options, also extend beyond Southeast Asia, though the specific additional regions are not detailed here.
