eSimfly eSIM Data Plans for Vietnam

eSimfly does not provide a truly unlimited data eSIM for Vietnam. All plans that carry the word “Unlimited” in their name actually have a fixed data allowance, marked as 1GB per day or 3GB per day, after which the speed may be throttled (the exact throttled speed is not listed in the data). If a user requires uninterrupted high‑speed data, a fixed‑data plan would normally be more suitable. For example, eSimfly offers a 50GB plan for 30 days at $41.75 USD or a 100GB plan for 180 days at $224.40 USD, both of which are valid specifically for Vietnam and come with tethering. These options provide larger data pools and can be more cost‑effective for heavy data users.

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 provides a total of 16 single‑country plans and 68 multi‑country plans for travelers in Vietnam. The single‑country plans allow you to purchase an eSIM only for Vietnam, while the multi‑country plans bundle coverage across multiple destinations but still include Vietnam. The catalog includes both fixed data amount plans, where the data cap is a set amount for the entire validity period, and daily data cap plans, where the data is capped each day. Prices for these plans range from $1.08 up to $224.40, and data caps span from 1 GB to 100 GB over validity periods of 1 to 365 days.
