Saily eSIM Data Plans for Vietnam

Saily does not provide a truly unlimited high‑speed eSIM for Vietnam. The plans that carry “UNLIMITED” in their name give a 5GB daily allowance; once the 5GB is used, the connection throttles to 1kbps. A similar throttling to 1kbps occurs after the 30GB monthly limit on the Global UNLIMITED 30‑day plan.

For travelers who need consistent high‑speed data without daily caps, Saily offers fixed‑data options. For example, the Vietnam 20GB 30‑day plan is priced at $28.99 USD, and the Asia and Oceania 25GB 60‑day plan covers Vietnam and 18 neighboring countries for $48.99 USD. These plans deliver full‑speed data for the entire validity period and can be more cost‑effective for heavy users.

Saily does not provide Vietnam eSIM plans that include a phone number or SMS service. Only data‑only eSIM plans are offered for travelers to Vietnam. Users can still communicate through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging without a traditional phone number.

Saily provides 11 single‑country data plans for Vietnam and 22 multi‑country plans that include Vietnam as one of the covered destinations. The available plans range in price from $3.99 to $159.99 and offer data caps from 1 GB up to 30 GB with validity periods of 5 to 365 days, allowing customers to choose between fixed data amounts and daily capped data depending on the selected plan.
