esimzon eSIM Data Plans for Vietnam

Esimzon does not offer a truly unlimited data eSIM for Vietnam. The plans that carry “Unlimited” in their names actually provide a fixed allowance of 25GB per day; once that daily limit is reached the speed is throttled to 8000kbps. If a traveler needs more data without a daily cap, esimzon offers large fixed‑data options, such as the 200GB plan valid for 30 days and the 750GB plan also valid for 30 days. These plans give a stable high‑speed connection for the entire validity period, avoiding the speed reduction that applies to the “Unlimited” offerings. Choosing a high‑cap fixed plan can be a more cost‑effective choice unless the user is a very heavy data consumer.

esimzon does not provide a Vietnam eSIM that includes a phone number or SMS capability. All of its Vietnam plans are data‑only, which means you will not receive a local phone number or be able to send or receive SMS messages with the plan.

Travelers who need to communicate can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. Because some destinations may block or restrict certain apps, it is advisable to check whether the VoIP services you rely on are accessible in Vietnam before purchasing a plan.

esimzon offers 3 single‑country plans and 18 multi‑country plans for Vietnam, a total of 21 data plans. The plans span a price range of $5.00 to $110.00 and cover data amounts from 1 GB to 750 GB. Among them there are 5 daily data cap plans, which provide a set amount of data every day during the validity period, and 16 fixed data cap plans, which give a total data amount that can be used throughout the plan’s duration. These options give travelers a variety of choices depending on how much data they need and how long they plan to stay.
