Frequently Asked Questions
Does ZenSim offer unlimited data eSIM for Vietnam?
ZenSim does not provide truly unlimited high‑speed data plans for Vietnam. The plans that carry the “Unlimited” label actually deliver a 3 GB/day cap; once the daily limit is reached the speed is reduced, although the specific throttled speed is not listed.
Instead, ZenSim offers fixed‑data plans that can be more cost‑effective for most travelers. For example, a 20 GB plan for 10 days is priced at $35.00 USD, and a 10 GB plan for the same validity is $20.00 USD. These options can suit users who need a reliable data allowance without the daily cap that applies to the “Unlimited” plans.
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. Only data‑only eSIMs are available.
Travelers can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, as these services do not require a local phone number or SMS feature.
How many data plans does ZenSim offer for Vietnam?
ZenSim offers eight single‑country plans and eight multi‑country plans that include Vietnam. The plans range in price from about $12 to $70 and carry data caps between 3 GB and 20 GB, with validity periods of 10 to 30 days. Within this selection, some plans provide a fixed data volume for the entire validity period while others impose a daily data cap that renews each day.
