MegaEsim eSIM Data Plans for Vietnam

MegaEsim does not provide a truly unlimited data eSIM for Vietnam. All plans listed have a specified data cap, and those labeled “Unlimited” are fixed‑data plans that offer a set amount of high‑speed data before speed is throttled.

If a large data allowance is desired, MegaEsim offers several fixed plans, such as the 10 GB/day plan valid for 1 day priced at $10.09 USD, the 5 GB/day plan valid for 1 day priced at $5.43 USD, and the 3 GB/day plan valid for 30 days priced at $148.26 USD. These plans give high‑speed data for a limited time and may be more cost‑effective than an unlimited option for most travelers.

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 and 65 multi‑country data plans for Vietnam. The available plans range in price from $1.29 to $302.82 and provide between 1 GB and 50 GB of data, with validity periods that can last from 1 to 365 days. Plans are available in both daily data cap formats—where the data allowance resets each day—and fixed data cap formats—where a set amount of data is used over the entire validity period.
