MegaEsim eSIM Data Plans for Vietnam

MegaEsim does not provide a truly unlimited data eSIM for Vietnam. The plans that include “Unlimited” in the name actually limit the high‑speed data to 1GB per day or 3GB per day; once the daily quota is reached the speed drops to 1000 kbps. Because the quantity of high‑speed data is capped, these plans are not unlimited in the strict sense.

Travelers who need more data without daily restrictions can choose MegaEsim’s fixed‑data plans. Examples include a 20GB plan valid for 30 days and a 50GB plan valid for 180 days, both offering uninterrupted 5G coverage throughout Vietnam. Fixed‑data plans can be more cost effective for heavy users who want to avoid the speed throttling that applies after the daily quota in the so‑called “Unlimited” plans.

MegaEsim does not currently provide eSIM plans for Vietnam that include a phone number or SMS capability. The available plans are data‑only, with no inbound or outbound voice or text service included.

Travelers can use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so it is advisable to verify that the services you rely on are accessible in Vietnam before purchasing.

MegaEsim offers 18 single‑country data plans for Vietnam and 30 multi‑country plans that can include Vietnam. Plan prices range from $1.29 to $243.60, and data caps span from 490 MB to 50 GB. Among the catalog, 16 plans feature daily data caps while 32 provide a fixed data amount, allowing users to choose between recurring daily limits or a single total data allotment.
