AlpineSIM does not provide a truly unlimited data eSIM for Vietnam. All of the plans that use the word “Unlimited” in their name actually have fixed data caps such as 500 MB, 1 GB, 2 GB, 5 GB, or 10 GB for the validity period. Once a user reaches the cap, the speed would be throttled, although the specific reduced speed is not listed.
If a traveler prefers a high‑data allowance, AlpineSIM offers fixed‑data eSIMs that can serve as alternatives. For example, the AlpineSIM Vietnam eSIM – 50 GB, valid for 180 days, is priced at $52.21 USD, and the AlpineSIM Vietnam eSIM – 20 GB, valid for 30 days, is priced at $17.61 USD. These fixed‑data plans can be more economical for those who do not need truly unlimited data.
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 8 single‑country plans and 146 multi‑country plans that include Vietnam. The available data limits range from 500 MB to 50 GB, prices span from about $0.65 up to roughly $287, and validity periods stretch from one day to one year. Some plans provide a fixed data amount, while others use a daily data cap. Tethering is allowed on many of the plans.
