BlueSky eSIM eSIM Data Plans for Vietnam

BlueSky eSIM does not provide a truly unlimited data plan for Vietnam. All plans that carry “Unlimited” in the name grant only 3GB of high‑speed data per day; once that allocation is used, the speed drops to 1000kbps and the plan is no longer considered unlimited.

If a user needs larger high‑speed data volumes, BlueSky eSIM offers fixed‑data options instead. For example, the 100GB plan is valid for 180 days, and the 50GB plan is valid for 90 days, both available on 5G networks in Vietnam. These fixed data plans can be more cost‑effective for travelers who prefer a predictable data allowance rather than the limited daily allowance of the “Unlimited” offerings.

BlueSky eSIM does not offer any Vietnamese eSIM plan that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for travellers wishing to use the service inside Vietnam.

If callers or receivers need to communicate via voice or text, they can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict these services, so users are advised to verify that the applications they rely on are accessible in Vietnam before purchasing a plan.

BlueSky eSIM offers a total of 11 single‑country plans and 29 multi‑country plans that include coverage in Vietnam. Across these packages the price range extends from about $1.52 to $100.15, with data caps spanning from 200 MB up to 100 GB. Validity periods vary between 3 and 365 days. The provider supplies both fixed‑data‑cap options—which provide a set amount of data for the entire validity period—and daily‑cap plans, which reset each day; the catalog contains 30 fixed‑data‑cap plans and 10 daily‑cap plans. The plans may also feature a reduced speed option of 1000 kbps in some cases, depending on the selected tariff.
