eSIMCard eSIM Data Plans for Vietnam

eSIMCard does not provide a truly unlimited data eSIM for Vietnam. The plans that contain “Unlimited” in their name actually include a daily data cap, such as 1 GB per day or 2 GB per day. Once the agreed‑upon amount is reached, the speed is throttled – to 512 kbps for 1 GB plans and to 2000 kbps for 2 GB plans.

If a traveler wants a higher data allowance, eSIMCard offers several fixed‑data options. For example, a 2 GB/day plan for 5 days or a 100 GB plan valid for 30 days are available. These higher‑cap plans give more data at a lower cost per unit than the “Unlimited” labeled plans, which can be more economical for most travelers.

eSIMCard does not provide a phone number or SMS capability for eSIM plans in Vietnam. Travelers can only purchase data‐only eSIMs from this provider. However, over the data connection standard VoIP applications such as WhatsApp, Telegram, and iMessage can usually be used for voice and messaging; availability may vary if a destination blocks or restricts specific apps, so passengers should confirm that the services they rely on are accessible in Vietnam before buying a plan.

eSIMCard offers 31 single‑country data plans and 100 multi‑country data plans for Vietnam. The single‑country collection includes plans that provide a fixed amount of data (e.g., 3 GB, 10 GB) for a set period, while the multi‑country range comprises plans that grant the same data allocation across several countries in Southeast Asia, useful for travelers who may move between Vietnam and neighbouring nations.

Among all plans, fixed data cap options amount to 75 different packages, whereas daily data cap plans total 56, allowing users to buy data by the day if that better fits their usage pattern. The price spectrum for eSIMCard’s Vietnam offerings ranges roughly from $2.88 to $395.07, with data caps spanning from 1 GB to 100 GB and validity periods that can last anywhere from a single day up to 180 days.
