Airalo eSIM Data Plans for Vietnam

Airalo does not provide a true unlimited high‑speed data plan for Vietnam. All plans that use the name “Unlimited” are limited to 3 GB of high‑speed data each day; once that limit is reached the speed is reduced to 1000 kbps.

Instead Airalo offers several fixed‑data options. For example, Asialink’s 100 GB plan is valid for 180 days and costs $89 USD, while Xin Chao’s 50 GB plan is valid for 30 days and costs $49 USD. These plans give a larger amount of full‑speed data and may be more cost‑effective for travelers who need a lot of data.

Airalo does not provide a Vietnam eSIM that includes a local phone number or SMS capability. The available plans for Vietnam are data‑only, allowing you to use your existing phone number for messaging and calls through data‑dependent apps such as WhatsApp, Telegram, or iMessage. These VoIP applications work over the data connection provided by the eSIM and can replace the need for a traditional phone number or SMS service while you travel.

Airalo offers 18 single‑country data plans for Vietnam and 35 multi‑country plans that include Vietnam. The plans range in price from $4 to $97, with data caps from 1 GB to 100 GB and validity periods of 3 to 365 days. Some plans provide a fixed data amount for the entire period, while others set a daily data cap, giving travelers the choice of the model that best matches their usage needs.
