ZenSim for Vietnam FAQ

Does ZenSim offer unlimited data eSIM for Vietnam?

ZenSim does not provide a true unlimited high‑speed data eSIM for Vietnam. All of its offerings have a hard data cap. For example, ZenSim sells a fixed data plan that gives 40GB of high‑speed data for 30 days at $44.10 USD, and another 20GB plan for 30 days at $25.20 USD. These plans allow continuous use within the allotted data amount without any speed reduction.

The plans that carry the word “Unlimited” in their name are actually 3GB per day, with the speed throttled to 1000 kbps after the daily limit is reached. Travelers who expect heavy data usage will typically find a larger fixed data plan cheaper and more reliable than the 3GB/day option.

Does ZenSim offer Vietnam eSIM with phone number and SMS?

ZenSim does not offer any eSIM plans for Vietnam that include a phone number or SMS capability. The provider only supplies data‑only eSIM plans in this country.

Travelers can still make voice or text communications by using VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict these apps. It is recommended that travelers verify that the VoIP applications they plan to use are accessible in Vietnam before purchasing a ZenSim eSIM.

How many data plans does ZenSim offer for Vietnam?

ZenSim offers 13 single‑country data plans and 18 multi‑country data plans that can be used in Vietnam. The plans vary in price from roughly $3.60 to $107.10 and provide data caps between 1 GB and 40 GB. Among the options, six plans feature a daily data cap, while the remaining plans offer a fixed data amount for the entire validity period.
