BlueSky eSIM eSIM Data Plans for Vietnam

BlueSky eSIM does not provide a truly unlimited high‑speed data eSIM for Vietnam. All plans labeled “Unlimited” grant 3 GB of 5G data each day; after the daily quota is reached the connection is throttled to 1000 kbps. For travelers who need more data, BlueSky eSIM offers fixed‑data alternatives such as a 100 GB plan valid for 180 days, a 50 GB plan valid for 90 days, or a 20 GB plan valid for 30 days, which provide larger total allowances without a daily cap.

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.
