JamboSim eSIM Data Plans for Vietnam

JamboSim does not provide a plan that offers truly unlimited high‑speed data for Vietnam. The only plans that carry “Unlimited” in their name give 3 GB of high‑speed data per day; after the 3 GB is used, the speed is throttled to 1000 kbps, so the data themselves are not unlimited.
If a traveler needs a larger, unrestricted data allowance, JamboSim sells fixed‑data plans such as 100 GB for 180 days, 50 GB for 90 days, and 20 GB for 30 days, which give a high‑speed data quota that is not capped on a daily basis. These fixed plans can be more cost‑effective for users who need more data but are not heavy‑data consumers.

JamboSim does not provide eSIM plans for Vietnam that include a local phone number or SMS capability. The only available offerings are data‑only eSIMs, allowing travelers to use the internet for browsing, email, and other data‑driven services. If a traveler needs voice or messaging, they can rely on internet‑based apps such as WhatsApp, Telegram, or iMessage that work over the data connection.

JamboSim offers 12 single‑country data plans and 33 multi‑country plans for travelers in Vietnam. Prices span from $1.99 to $94.99 and data caps range between 200 MB and 100 GB. Among these, 12 plans use a daily data cap—limiting usage day‑by‑day—while 33 employ a fixed data amount that can be consumed at a single rate over the validity period.
