CloudOn eSIM eSIM Data Plans for Vietnam

CloudOn eSIM does not provide a truly unlimited high‑speed data plan for Vietnam. The plans that carry the word “unlimited” in their name actually allot 2GB per day, and once that limit is reached the speed is throttled to 1000 kbps. Because of the capped data allowance, the term “unlimited” is misleading; the plans are essentially fixed‑data packages with a reduced speed after the daily quota is used.

For travelers who need higher data volumes without such throttling, CloudOn eSIM offers several fixed‑data options. For example, a 50 GB plan valid for 30 days is priced at $35.99 USD, and a 20 GB plan for 30 days costs $16.99 USD. These plans provide more data at full speed and are suitable for users who expect heavy data usage while visiting Vietnam.

CloudOn eSIM does not provide a Vietnam eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for travel in Vietnam. Travelers can still use voice and messaging through popular VoIP applications such as WhatsApp, Telegram, and iMessage, which work over the data connection without requiring a local phone number.

CloudOn provides 12 single‑country data plans and 25 multi‑country data plans that can be used in Vietnam. These plans span a price range of about $3.49 to $177.49 and offer data caps from 500 MB up to 100 GB, with options for both fixed data amounts and daily data caps.
