Audio & calls

Wi-Fi calling not working

This is usually caused by Wi-Fi Calling being disabled, a weak Wi-Fi network, or the feature not being set up with the carrier. Checking settings and network strength fixes most cases.

Symptoms

  • Wi-Fi Calling toggle appears off or greyed out

Likely causes

  • CommonWi-Fi Calling turned off in settingsThis feature must be manually enabled and isn't always on by default.
  • CommonWeak or unstable Wi-Fi connectionWi-Fi Calling needs a decent, stable connection to place and hold calls.
  • PossibleCarrier hasn't provisioned Wi-Fi Calling for the lineSome plans or older accounts need the carrier to enable this feature first.
  • PossibleEmergency address not set for Wi-Fi CallingMany carriers require a registered address before allowing the feature to activate.
  • Less commonRouter or network blocking VoIP trafficSome routers or public Wi-Fi networks restrict the type of traffic Wi-Fi Calling uses.

What to do

  1. Go to Settings > Phone > Wi-Fi Calling (or Settings > Connections > Wi-Fi Calling on Android) and confirm it's turned on.
  2. Check that the Wi-Fi connection is strong and stable, moving closer to the router if needed.
  3. Complete or update the emergency address requirement if prompted, since many carriers block the feature until this is set.
  4. Restart the phone after enabling the feature.
  5. Try a different Wi-Fi network, especially if on public or restricted Wi-Fi.
  6. Toggle Wi-Fi off and back on to refresh the connection.
  7. Check for a carrier settings or software update.
  8. If the toggle stays greyed out or unavailable, contact your carrier to confirm Wi-Fi Calling is enabled on your line.

When to call a pro

If Wi-Fi Calling stays unavailable or greyed out after checking settings, your carrier needs to enable it on your account.
