Wi-Fi calling is a feature offered by wireless carriers such as AT&T, Verizon, and T-Mobile that allows users to make calls, send texts, and video calls over their home internet connection. This can be useful in situations where cellular service is unavailable, such as during a widespread outage. Wi-Fi calling is available on a wide range of devices, including smartphones and basic flip phones, and can be used as a primary means of communication if the home internet connection is fast enough. In addition to traditional phone services, Wi-Fi calling also allows for the use of other chat and calling apps, such as FaceTime and iMessage on iPhone, and Google Meet and RCS texting on Android.
To enable Wi-Fi calling on an iPhone, users can access the feature through the Settings app, select the Cellular option, choose the line they want to enable Wi-Fi calling for, and turn on the feature. Users will be prompted to input their address for emergency services, and their device’s location information may be used for emergency calls. The device’s status bar will reflect that calls and texts are routed through Wi-Fi, and users can also allow other Apple devices to make Wi-Fi calls when the iPhone is not nearby. Android phones also offer Wi-Fi calling, with the steps to enable the feature varying depending on the device.
Basic phones that work on 4G networks often include Wi-Fi calling as well, with steps for setup varying based on the specific phone. In the event of a cellular outage, users can access Wi-Fi hotspots set up by internet service providers, such as Optimum on Long Island in New York. Local libraries and coffee shops that offer Wi-Fi access are also alternative options to stay connected during an outage. Some newer technologies, such as Emergency SOS via Satellite on the iPhone 14 and iPhone 15, provide a backup for situations where users have no access to cellular service. Samsung has also announced plans to develop satellite connectivity options for future Android phones.
Overall, Wi-Fi calling is a versatile feature that extends the capabilities of mobile phone services through the use of home internet connections. It can serve as a reliable backup during cellular outages, allowing users to stay connected for necessary calls and messages. With easy setup on smartphones, basic phones, and other devices, Wi-Fi calling is a convenient option for maintaining communication in various situations. Additionally, access to Wi-Fi hotspots and emerging technologies like Emergency SOS via Satellite provide further options for staying connected when cellular service is unavailable.
