Ovosim eSIM Data Plans for Vietnam

Ovosim does not provide an unlimited data eSIM for Vietnam. The catalog includes only fixed‑data plans, the most common of which offer 20 GB of high‑speed data. For example, there is a “Vietnam 20GB ‑ 5 Days” plan valid for six days, a “Vietnam 20GB ‑ 10 Days” plan valid for eleven days, and a “Vietnam 20GB ‑ 15 Days” plan valid for sixteen days. These options are priced between about $35 and $39 USD, depending on the chosen validity. Fixed data plans can be more cost‑effective for travelers who do not need truly unlimited usage; for very heavy data users a larger‑cap plan may be a better fit.

Ovosim does not provide a Vietnam eSIM that includes a local phone number or SMS capability. The service from this provider is limited to data‑only plans, so travelers will not receive an inbound or outbound voice or text service through the eSIM.
To communicate while abroad, users can rely on VoIP applications such as WhatsApp, Telegram or iMessage, which use the available data connection for calls and messaging without needing a separate phone number or SMS feature.

Ovosim offers 20 single‑country data plans and 40 multi‑country data plans for use within Vietnam. The plans vary in price from around $5.27 to $117.26 USD, provide data caps between 1 GB and 20 GB, and have validity periods ranging from 6 to 31 days.
