Lumbus eSIM Data Plans for Vietnam

Lumbus does not provide a truly unlimited eSIM for Vietnam. The plans that carry the name “Unlimited” actually allow 3 GB of high‑speed data per day; once that daily limit is reached the speed is throttled to a reduced rate.

If a traveler needs more data without a daily cap, Lumbus offers fixed‑data plans such as a 50 GB plan valid for 180 days at $90.99 USD or a 20 GB plan valid for 30 days at $35.99 USD. These options may be more cost‑effective for users with high data needs.

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 12 single‑country plans and 41 multi‑country plans that include Vietnam, bringing the total to 53 distinct data options. Prices across the catalogue range from about $2.99 to $179.99, while data caps vary from roughly 500 MB up to 50 GB. The offerings include both daily cap plans, in which the data allowance refreshes each day, and fixed cap plans, which provide a fixed total amount of data for the entire validity period. This mix allows travelers to choose between regular daily data refreshes or a larger, cumulative data bundle for longer stays.
