What is VoWiFi?
VoWiFi or Voice over WiFi, allows you to make and receive calls and text messages over a Wi-Fi network instead of relying solely on a cellular signal. It works seamlessly on your phone’s background so your calls look and feel the same as regular calls, but they connect through Wi-Fi when cellular coverage is weak or unavailable. It combines convenience, reliability and quality ensuring your phone works for you anywhere Wi-Fi is available.
Why is VoWiFi Important?
- Stronger indoor coverage when walls or buildings can weaken cellular signals.
- No Extra Apps Needed – it uses your phone’s built-in dialer and messaging, so no separate apps or logins are required.
- Cost Savings while roaming – Some carriers allow Wi-Fi calling abroad without adding roaming charges, making it easier to stay connected without worrying about high fees.
- Enhanced Call Quality – Wi-Fi calling often provides sharper voice quality and fewer dropped calls compared to a weak cellular service.
