AlpineSIM eSIM Data Plans for Vietnam

AlpineSIM does not provide a true unlimited data eSIM for Vietnam. All of the plans marketed as “Unlimited” in the provider’s catalogue have a fixed data cap, ranging from 500 MB per day up to 10 GB per day, and the plans expire after one to fifteen days. Because the data allowance is limited, the network speed does not automatically drop to a low tier after the cap is reached, but no plan offers unlimited high‑speed data.

Travelers who need more data for an extended stay can choose from AlpineSIM’s fixed‑data options. For example, the AlpineSIM Vietnam eSIM with 20 GB for 30 days and the AlpineSIM Vietnam eSIM with 50 GB for 180 days provide large, predictable data allowances. These plans are often more cost‑effective for heavy data users than the short‑duration “Unlimited” plans.

AlpineSIM does not provide eSIM plans for Vietnam that include a phone number or SMS capability. Only data‑only eSIMs are available from the provider for travelers visiting Vietnam.

Travelers can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. These apps enable voice calls and messaging without the need for a local phone number or SMS service.

AlpineSIM offers 9 single‑country data plans for Vietnam and 146 multi‑country plans that include Vietnam. Prices range from $0.14 to $300.22, data limits span 100 MB to 50 GB, and validity periods vary from 1 to 365 days. The provider supplies both fixed‑data plans, which provide a set amount of data for the entire validity period, and daily‑data‑cap plans, which limit the amount of data that can be used each day.
