How can I guarantee top-notch coverage at home or in the office?
With WiFi Calling, you can easily make and receive calls and texts in any Wi-Fi-enabled location in New Zealand, even if your mobile signal is weak. WiFi Calling, like VoLTE, functions as a standard call over a stable WiFi connection. It’s ideal for use at home, work, or in areas with limited coverage.
