Yes, of course, Vietnam's international airports have wifi.

Access to the Internet via a wireless Wi-Fi network is available in the business halls of the international airport of Ho Chi Minh City Tan Son Nhat (Tan Son Nhat International Airport). However, according to reviews of many tourists, you can "catch" free Wi-Fi in other halls of the airport. The connection speed is small, but to see the weather, check the exchange rate or read the latest news, it should be enough.

This service is at the stage of rapid development and will soon be available at other airports in the country. Wi-fi in Vietnam is available in most hotels, in many cafes and restaurants, even on the streets in some tourist areas.
