Ufone VoWiFi - Ufone 5G

Ufone VoWiFi

VoWiFi, or Voice over Wi-Fi- commonly known as Wi-Fi Calling, is a smart calling technology that lets you make and receive crystal-clear voice calls over any Wi-Fi network instead of relying on cellular coverage.

Whenever your mobile signal is weak or unavailable, your phone automatically routes your calls through your Wi-Fi connection, keeping you connected without interruption.

The best part? Everything happens through your phone’s native dialer using your existing Ufone number, no extra apps, no separate logins, and no changes for the person on the other end of the call.

Whether you’re in a basement, a high-rise building, a thick-walled structure, or a remote area where cellular signals struggle to reach, VoWiFi ensures your conversations remain smooth, clear, and uninterrupted.

Say hello to calling that follows you wherever there’s Wi-Fi.

Benefits

  • Stay connected in low-signal areas, make and receive calls in basements, elevators, concrete buildings, and remote locations, as long as you have a Wi-Fi connection.
  • No extra apps required, use your phone’s built-in dialer and your existing Ufone number.
  • Enjoy crystal-clear HD voice quality over your home or office internet connection.
  • Save battery life by avoiding the constant search for a distant cell tower.
  • Seamless handover, calls automatically switch between Wi-Fi and VoLTE as you move in and out of coverage, helping prevent dropped calls.

How VoWiFi Works

Instead of routing your voice calls through a cell tower, VoWiFi converts them into data packets and securely transmits them over your Wi-Fi network to the Ufone network.
The result is dependable, high-quality calling wherever you have a stable internet connection, whether at home, in the office, or while travelling abroad.
