Saily eSIM Data Plans for Vietnam

Saily does not provide a true unlimited data eSIM for Vietnam. All of its Vietnam‑specific plans have a fixed high‑speed data allowance, such as 5GB per day for up to 30 days, 20GB for 30 days, or 10GB for 30 days. After the allocated limit is reached, the plan’s speed is reduced, which is common for “unlimited”‑named plans that actually contain a capped data pool. For travelers who need large amounts of data but want a predictable cost, the 20GB‑30‑days or 10GB‑30‑days offerings are examples of fixed‑data alternatives that can be more cost‑effective than the high‑price “UNLIMITED” options.

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 offers 11 single‑country plans and 17 multi‑country plans for Vietnam. The plans span a price range of about $3.99 to $81.99 and data caps from 1 GB up to 30 GB, with validity periods between 5 and 365 days. Some plans feature a daily data cap of up to 12, while others use a fixed data cap of up to 16, allowing users to choose between a set amount of data for the entire validity or a daily allowance.
