JamboSim eSIM Data Plans for Vietnam

JamboSim does not provide a truly unlimited high‑speed data plan for Vietnam. Every plan that uses the word “Unlimited” in its name actually offers only 3GB per day, and once that daily limit is reached the speed drops to 1000kbps. Therefore the data is capped rather than unlimited in the sense of continuous, unrestricted high‑speed connectivity.

Instead, JamboSim offers fixed‑data eSIMs that give larger amounts of high‑speed data for a set period. For example, the 20GB plan is valid for 30 days at $10.99 USD when purchased as a JamboSim Asia plan, and the 100GB plan is valid for 180 days at $71.99 USD. These fixed‑data options may be more cost effective for travelers who need a high data allowance while staying in Vietnam.

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 a range of data plans that cover Vietnam, comprising 12 single‑country plans and 49 multi‑country plans. The single‑country plans are fixed‑data caps, allowing travelers to purchase a set amount of data—ranging from 200 MB up to 100 GB—for a period that can extend up to 365 days, with prices between $1.99 and $125.99. The multi‑country plans include daily‑cap options, giving users flexibility to use a specified amount of data each day across multiple destinations, with similar validity and price ranges. In total, 61 distinct plans are available to use in Vietnam.
