BlueSky eSIM eSIM Data Plans for Vietnam

BlueSky eSIM does not provide a truly unlimited data plan for Vietnam. Plans that include “Unlimited” in the name, such as the Vietnam — BlueSky eSIM (Unlimited/3d), actually deliver only 3 GB per day of high‑speed data; once the daily allowance is used, the speed is throttled to 1000 kbps. The data cap is applied daily and the plan is valid for the specified number of days.

Instead, BlueSky eSIM offers fixed‑data alternatives that may be a better fit depending on usage. For example, a 20 GB plan for 30 days costs $29 USD, while larger options such as 50 GB for 90 days and 100 GB for 180 days are also available. These plans give a set amount of high‑speed data without daily throttling, which can be more cost‑effective for travelers who need consistent connectivity.

BlueSky eSIM does not offer a Vietnam eSIM with a phone number or SMS capability. Only data‑only plans are available for Vietnam, and callers must rely on data connections. Puerto utilise VoIP services such as WhatsApp, Telegram, or iMessage over the data link for voice calls and text messaging.

BlueSky eSIM offers 11 single‑coverage plans that cover Vietnam and an additional 30 multi‑coverage plans that include Vietnam. The available plans range in price from $1.97 to $89 and provide data amounts between 200 MB and 100 GB, with validity periods spanning from 3 to 365 days. Within these offerings, fixed‑data‑cap plans deliver a set amount of data for the plan’s duration, whereas daily‑cap plans reset the data allowance each day.
