Tech Explained: What is Wi Fi Calling?

Kokila Chokkanathan
Wi‑Fi Calling is a feature offered by mobile operators that allows you to make voice calls and send texts over a Wi‑Fi network instead of relying solely on a cellular network. This can be particularly useful in areas with poor mobile coverage.

How Wi‑Fi Calling Works

When you enable Wi‑Fi Calling on your smartphone:

  • Your phone connects to a Wi‑Fi network instead of the cellular network for calls.
  • Calls are routed through the internet securely to your carrier’s network.
  • You can make and receive calls or send texts just like a normal phone call.
This is especially helpful indoors or in remote areas where cell signal is weak but Wi‑Fi is available.

Benefits of Wi‑Fi Calling

Clearer Voice Quality

Calls over Wi‑Fi often have better audio clarity, reducing dropped or distorted calls.

Works Indoors and in Basements

Even if your mobile network signal is poor at home or office, you can stay connected.

No Extra App Needed

Unlike VoIP apps (WhatsApp, Zoom), Wi‑Fi Calling works directly through your phone’s native dialer.

Seamless Handover

Some devices and networks allow calls to switch automatically between Wi‑Fi and mobile networks without dropping.

How to Enable Wi‑Fi Calling

On most smartphones:

  • iPhone: Settings → phone → Wi‑Fi Calling → Enable
  • Android: Settings → Connections → Wi‑Fi Calling → Enable
Note: Your carrier must support Wi‑Fi Calling, and some may require you to register your address for emergency services.

When to Use Wi‑Fi Calling

  • In areas with weak or no cellular signal
  • While traveling abroad if your carrier allows Wi‑Fi Calling internationally
  • At large buildings or underground locations where mobile reception is limited
Wi‑Fi Calling is a simple yet powerful feature that ensures you stay connected, no matter where you are — and you don’t even need a strong mobile signal to enjoy clear, reliable voice calls.
