Roamic eSIM Data Plans for Vietnam

Roamic does not provide a truly unlimited data eSIM for Vietnam. The plans labeled “Unlimited” actually offer a fixed high‑speed data allowance of 3GB per day (or 3GB for the entire validity period) before the speed is reduced. For travelers who need more data, Roamic sells fixed‑cap plans such as 20GB for 30 days at $27.77 USD, 10GB for 30 days at $13.88 USD, or 5GB for 21 days at $9.25 USD. Choosing a fixed data plan can often be more cost‑effective, especially for users who are not heavy data consumers.

Roamic does not provide a phone number or SMS capability for its Vietnam eSIM plans. Only data‑only eSIMs are available from this provider in Vietnam.

Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

Roamic offers 13 single‑country plans that cover Vietnam alone, and an additional 13 multi‑country plans that include Vietnam in their coverage. These plans span a price range from roughly $2.32 up to $174.62 and provide data caps between 1 GB and 20 GB. Some of the options are fixed‑data plans, giving a set amount of data for the entire validity period, while others are daily‑cap plans, where the data allowance refreshes each day during the validity window.
