Can You Still Chat on Skype Without Wi-Fi?

In order to use Skype for chatting or calls, you must have an Internet connection. If you are using Skype on a computer and don't have Wi-Fi, you can use a standard wired Ethernet connection. Skype also offers a mobile application, which you can download to your smart phone. Once you are logged on to the app, you can chat with friends using the phone's 3G or 4G data connection. Text chat works well over all connections, but Skype recommends the use of Wi-Fi for voice or video calls.
