Saily eSIM Data Plans for Vietnam

Saily does not offer a truly unlimited high‑speed data eSIM plan for Vietnam; all plans that carry “Unlimited” in the name have a defined daily data cap and specify a reduced speed once that limit is reached. For example, the “Vietnam UNLIMITED 5GB/day” plan gives 5GB of high‑speed data each day and drops to 1 kbps after the cap is hit.

Travelers who need more predictable data usage can choose from Saily’s fixed data plans, such as the Vietnam 20GB 30 days plan at $28.99 USD or the Asia and Oceania 25GB 60 days plan at $48.99 USD, both offering consistent speed throughout the validity period. These alternatives can be more cost effective for users who consume a large amount of data.

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.
