eSimfly eSIM Data Plans for Vietnam

eSimfly does not provide a truly unlimited data eSIM for Vietnam. Its plans that carry the word “Unlimited” are actually capped at 3 GB per day for the stated validity period, meaning the data is limited and the speed is not guaranteed to remain high after the daily quota is reached. Travelers who require more generous data allowances can choose from eSimfly’s fixed‑data options, such as the 20 GB plan valid for 30 days or the 100 GB plan valid for 180 days. These fixed plans offer larger cumulative data and can be more cost‑effective for users who need extensive high‑speed connectivity in Vietnam.

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 offers 15 single‑country data plans for Vietnam, and it also has 27 multi‑country plans that include Vietnam as part of a broader coverage area. The single‑country plans provide data usage exclusively within Vietnam for the plan’s validity period, while the multi‑country plans allow data to be used in multiple destinations without changing the plan. Price points range from $1.08 to $90.60, and data caps vary between 1 GB and 100 GB. Some plans feature a fixed data amount, whereas others impose a daily data cap, and tethering is allowed on plans that specify it.
