MegaEsim eSIM Data Plans for Vietnam

MegaEsim does not provide a truly unlimited data eSIM for Vietnam. The plans that carry the word “Unlimited” in their name actually have a daily data allowance and a reduced speed after that limit is reached. For example, the Vietnam Unlimited, 1 GB/day plan gives full speed for 1 GB per day and then throttles to 1 Mbps, while the Vietnam Unlimited, 3 GB/day plan offers full speed for 3 GB per day before throttling. These are fixed data plans with clear caps.

Travelers can choose from a range of fixed data plans that cover Vietnam, such as the 1 GB/day plan valid for 30 days, the 3 GB/day plan valid for 30 days, or larger bundles like 50 GB for 180 days. These plans provide a defined data allowance and are often more cost‑effective unless the user is an extremely heavy data consumer.

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 provides 18 single‑country data plans that cover Vietnam, with data allowances ranging from 490 MB to 5 GB and prices between roughly $1.30 and $28.40. In addition, 45 multi‑country plans that include Vietnam are available; these plans can provide up to 50 GB of data and are priced up to about $244, depending on the validity period. The provider offers both fixed‑data‑cap options, where a total data amount is allocated for the entire period, and daily‑cap options, where data is available in a set amount each day during the validity window.
