Airalo eSIM Data Plans for Vietnam

Airalo does not provide a truly unlimited high‑speed data plan for Vietnam.
The plans that carry “Unlimited” in their name give 3 GB per day and, after that limit is reached, the speed is reduced to 1000 kbps.

Travelers who need more data can choose a fixed‑data plan. For example, the Asialink 100 GB plan is valid for 180 days and costs $89.00 USD, and the Xin Chao 50 GB plan is valid for 30 days for $49.00 USD. These fixed‑data options tend to be more cost‑effective for heavy data users.

Airalo does not offer Vietnam eSIM plans that include a phone number or SMS capability. Travelers who rely on a local number for calling or texting will need to use data‑only Airalo eSIMs and then use VoIP services such as WhatsApp, Telegram, or iMessage for voice and text communication. While these apps generally work over the data connection, some destinations may block or restrict specific VoIP services, so travelers should confirm that the services they depend on are accessible in Vietnam before purchasing an eSIM.

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.
