What is Wi-Fi calling and how does it work?
Wi-Fi calling is a feature that allows users to make voice calls over a Wi-Fi network instead of using their cellular network. This feature uses Voice over Internet Protocol (VoIP) technology to connect calls, which means that it converts voice signals into digital data and transmits them over the internet. When a user makes a call using Wi-Fi calling, their phone connects to a nearby Wi-Fi network and uses it to establish a connection with the recipient’s phone.
Wi-Fi calling works by using the internet connection to establish a communication channel between the caller and the recipient. This allows users to make calls even when they don’t have a strong cellular signal, as long as they have a stable Wi-Fi connection. Wi-Fi calling also allows users to make international calls at a lower cost, as they are not charged for roaming or long-distance calls. Additionally, Wi-Fi calling can provide better call quality and fewer dropped calls, as it uses the internet connection to transmit voice signals.
Do I need a cellular plan to use Wi-Fi calling?
In most cases, yes, you need a cellular plan to use Wi-Fi calling. Wi-Fi calling is typically offered by cellular carriers as an additional feature to their plans, and it requires a cellular account to activate and use the feature.
