Ovosim eSIM Data Plans for Vietnam

Ovosim does not provide a truly unlimited high‑speed data eSIM for Vietnam. The plans that use the word “Unlimited” actually give a fixed daily allotment—from 2 GB per day up to 5 GB per day—and the total amount of data is capped by the validity period. After that limit is reached, the speed would be throttled, but no specific reduced speed is listed, so the plan is effectively a limited‑data offer.

For travelers needing more data, Ovosim sells fixed‑data plans such as the Vietnam 20GB 30Days plan for $32.40 USD or the Vietnam 50GB 180Days plan for $104.16 USD. These options give a larger high‑speed data allowance and can be more cost‑effective for heavy usage.

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 a wide selection of plans in Vietnam, ranging from $4.62 to $115.74, with data caps between 1 GB and 51 GB over validity periods of 5 to 180 days. In the single‑country catalog there are 39 distinct Ovosim plans for Vietnam, while the multi‑country catalogue contains 52 Ovosim packages that include Vietnam. The catalog features both fixed‑data‑cap plans, which provide a set amount of data for the entire validity period, and daily‑data‑cap plans, which allocate a fixed daily data allowance that adds up to the same total over the period. Thus, Ovosim offers 39 single‑country and 52 multi‑country data plans for travelers visiting Vietnam.
