3 Points to Note When Using Free Wi-Fi at Airports


Free Wi-Fi at airports is convenient and free. However, there are three major points to keep in mind when using this service. Check them carefully and prepare a communication environment suitable for your own smartphone usage at the airport.

Caution 1: Free Wi-Fi at airports can be slow

Free Wi-Fi at airports may be accessed by many people at once, and the speed may be slower than rental Wi-Fi or your fixed Wi-Fi at home. We actually conducted a speed survey and found that some spots at some airports had speeds that were almost the same as when speeds were limited, so be careful if speed is important to you.

Caution 2: Free Wi-Fi at airports may not work as soon as you connect.

Most free Wi-Fi at airports will not allow you to open a browser to view a site without going through a single step, such as checking the terms of use and registering for use. In addition, the speed at which you can make those settings is also difficult to crack through, when caution point (1) is taken into account.

Caution 3: Beware of security when using free Wi-Fi at airports.

Some free Wi-Fi at airports can be used without entering a password. While this is a convenient way to quickly connect to Wi-Fi, it also poses the risk of unauthorized access or virus infection, as the communication is not encrypted. In addition, it has been confirmed that some Wi-Fi systems have been set up with fake Wi-Fi IDs that closely resemble those of the free Wi-Fi at airports, and the information of those who have accessed the system by mistake is extracted. When using free Wi-Fi at airports, avoid sending personal information or using credit cards.

Mobile Wi-Fi rentals are an option!

Free Wi-Fi at airports is free and very convenient, but you need to be careful when using it in terms of "speed," "setting method," and "security. If you need to use the Internet immediately after arriving at the airport, use the free Wi-Fi at the airport. If you need stable speed and high security, use rental Wi-Fi.
