eSimfly eSIM Data Plans for Southeast Asia

eSimfly does not provide a plan that offers unlimited high‑speed data in Southeast Asia. The plans that list “Unlimited” in the name all include a 1GB data cap; once that limit is reached the speed is reduced. This applies to the Southeast Asia Unlimited 1 day, 20 days, 25 days and the Asia Unlimited 1‑day, 3‑day, 5‑day, 20‑day, 30‑day options.

Instead, eSimfly sells fixed‑data plans that cover the same region. For example, a 100GB plan valid for 180 days and a 50GB plan also valid for 180 days cover Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand and Vietnam (the 50GB plan also includes a few additional countries). These plans may be more economical for travelers who need a larger data allowance without the need for a truly unlimited tier.

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.

eSimfly’s eSIM plans cover Indonesia, Malaysia, Singapore, Thailand, Vietnam, Cambodia, Laos, the Philippines, Brunei, and Timor‑Leste, providing connectivity across the majority of Southeast Asian countries.
