eSimfly eSIM Data Plans for Vietnam

eSimfly does not provide a truly unlimited data eSIM for Vietnam. All plans that carry “Unlimited” in the name actually give a fixed amount of high‑speed data, such as 1 GB per day or 3 GB per day. Once that daily quota is used, data bandwidth is reduced or speeds are throttled, but the plans are not unlimited in the sense of providing unrestricted high‑speed usage.

For travelers who need larger data allowances, eSimfly offers fixed‑data plans such as Vietnam 20 GB 30 days and Asia 50 GB 90 days, as well as Asia 100 GB 180 days. These plans provide a set amount of data for a set validity period and can be more cost‑effective for heavy data users when compared to the daily‑quota “Unlimited” plans.

eSimfly does not offer a Vietnam eSIM that includes a phone number or SMS capability. The provider only sells data‑only eSIM plans for Vietnam, so travelers cannot make or receive standard voice calls or send SMS through the eSIM. If phone calls or text messages are needed, they can be made and sent with VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection.

eSimfly lists 15 single‑country data plans for Vietnam and 57 multi‑country plans that include Vietnam. These plans cover a wide range of options, with prices ranging from about $1.08 to $257.40 and data caps between 1 GB and 100 GB. Validity periods span from one day up to a full year (365 days). Among the packages, 13 feature daily data‑cap limits while the remaining 59 offer fixed data amounts. This variety enables travelers to choose a plan that fits both budget and usage needs.
