Lumbus eSIM Data Plans for Vietnam

Lumbus does not provide a truly unlimited data eSIM for Vietnam. The plans that carry the name “Vietnam Unlimited” give 3 GB of high‑speed data per day and, after the daily limit is reached, the speed drops to 1000 kbps. No plan offers unlimited high‑speed data.

Instead, Lumbus offers fixed data plans that can be suitable for most travelers. Examples include a 50 GB plan that is valid for 180 days and a 20 GB plan that is valid for 30 days, both providing high‑speed 5G data and tethering. Selecting a fixed‑data package can be more cost‑effective for users who do not need constant unlimited connectivity.

Lumbus does not offer an eSIM in Vietnam that includes a phone number and SMS. Only data‑only eSIM plans are available. Travelers wishing to make voice calls or send text messages can use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may block or restrict access to these applications, so it is advisable to confirm that the apps are accessible in Vietnam before purchasing.

Lumbus offers 11 single‑country data plans for Vietnam and 38 multi‑country plans that include Vietnam. Among all plans the provider lists 45 fixed data cap options and 4 daily data cap options. Prices span from about $3.99 to $140.99 while data caps range from 1 GB up to 50 GB, giving customers a wide selection of short‑term to long‑term options.
