JamboSim eSIM Data Plans for Vietnam

JamboSim does not provide a truly unlimited data eSIM for Vietnam; all its plans include a capped high‑speed allowance. The plans that use “Unlimited” in their name provide 3GB per day of high‑speed data, after which speed is throttled to 1000 kbps.

Fixed data options are available instead. For example, the eSIM JamboSim Asia 20GB plan for 30 days in Vietnam costs $10.99 USD, and the eSIM JamboSim Asia 100GB plan for 180 days costs $69.99 USD. These plans give large high‑speed data allowances without the daily limit, making them a more cost‑effective choice for most travelers unless they require continuous, unthrottled connectivity.

JamboSim offers eSIM plans for Vietnam that include a phone number and outbound SMS capability. The plans start at $11.99 USD for 1GB of data valid for 7 days and go up to $101.99 USD for 20GB valid for 365 days. Each plan provides a phone number with the dialing code +1 and supports outbound voice calls and outbound SMS messages.

Because the dialing code is +1, the phone number is a U.S. number rather than a local Vietnamese number. If travelers need inbound calls or SMS, or a local Vietnamese number, they should confirm the exact features directly with JamboSim before purchasing.

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.
