What is Wi-Fi Calling?+
Wi-Fi Calling, also known as VoWiFi (Voice over Wi-Fi), allows customers to make and receive voice calls and SMS using a Wi-Fi network directly from the phone’s native dialer, even when mobile coverage is weak or unavailable (such as basements or deep indoor areas). No additional app is required.
Do I need to install an app?+
No. Wi-Fi Calling is built into your phone. If your handset supports it, you simply switch it on in Settings — there is nothing to download.
Can I use Wi-Fi Calling if the other party does not support it?+
Yes. The other party does not need Wi-Fi Calling or VoLTE.
