When you're on the go and want to connect to the Internet with your iPhone using Wi-Fi instead of a cellular data network, you could find that the Wi-Fi hotspots detected by the device have a lock icon next to their name, indicating that you need to type a password to gain access. The iPhone has a touch-sensitive display and comes with a variety of apps already installed that you can use while connected to the Internet, such as the Safari Web browser and FaceTime for making free video calls. When a Wi-Fi network is locked, you'll need to ask someone for its password.
