Frequently asked questions
Wi-Fi calling allows you to send and receive text messages or phone calls completely through a Wi-Fi connection, rather than relying on a mobile network signal.
4G calling, also known as “Voice over LTE”, allows you to make calls using data. The main benefit of 4G calling is its high-definition audio quality compared to standard network calls. When it’s turned on alongside Wi-Fi calling, your phone will automatically move between Wi-Fi and 4G data to keep the call connected.
When you are on a Wi-Fi network and try to make a call or send a text, your phone will automatically select the best network to use. So if you have a poor phone signal but strong Wi-Fi, you’ll automatically use Wi-Fi calling. If you have no Wi-Fi connection, Wi-Fi calling will not work.
No, Wi-Fi calling does not use any mobile data.
