JamboSim eSIM Data Plans for Vietnam

JamboSim does not provide a truly unlimited high‑speed data eSIM plan for Vietnam. Their “Unlimited” plans offer 3GB of high‑speed data each day; once the 3GB is used, the speed drops to 1000kbps. This limitation means the plans are not genuinely unlimited.

Travelers who need more data without daily limits can choose from JamboSim’s fixed‑data options. For example, a 20GB/30‑day plan for $20.99 USD or a 100GB/180‑day plan for $71.99 USD are available, providing larger totals of high‑speed data, which can be a more cost‑effective choice for heavy users.

JamboSim provides eSIM plans for travelers in Vietnam that include a phone number and the ability to send SMS. The plans range from 1GB of data valid for 7 days to 20GB of data valid for 365 days, with prices ranging between $11.99 and $105.99 USD. Each plan offers a phone number dialed from the +1 code and supports outbound voice calls and outbound text messages only, while inbound calls and messages are not supported. Travelers who need additional or specific telephony features should confirm the details directly with JamboSim.

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.
