  • Charge your smartphone to its maximum capacity and connect it to WiFi.
  • Swipe down the notification bar and select Settings Menu.
  • Now, scroll down and select Software Update (For iOS Go To General->Software Update).
  • After that, choose Manually Download Updates From Your Mobile Screen.
  • Installing the update is as simple as following the on-screen instructions.
  • After the installation is complete, wait for the device to restart on its own.

Make sure that your WiFi network is switched On. Also, make sure that it can search the available WiFi network nearby. This can help you ensure that your WiFi is working.

Otherwise, tap on Airplane Mode, wait about 30 seconds and then tap on Airplane Mode again to ensure that it is disabled and all of your cellular connections, including the WiFi connection, are back to normal.

Most of the time, your WiFi network becomes stuck, and enabling and then disabling Airplane mode can help you resolve the WiFi Calling not working issue. You can also try restarting your smartphone.

4. Turn Off Your Mobile Data And Try

After you have used Airplane Mode to refresh all of your connections, you may want to experiment with turning off your mobile data connection altogether. As a result, your device will only be able to communicate with your network via Wi-Fi.

To temporarily disable cellular data on your smartphone, follow the steps below.

  • To access the Quick Settings Panel, click on the Quick Settings button.
  • Wait a minute after tapping the Data icon.
  • Re-tap the Data icon.

5. Check Your Internet Connection

You must have a working internet connection with a minimum speed of 15Kbps in order to continue using WiFi Calling. Internet Explorer can be used to check the speed of your connection.

6. Contact AT&T Customer Service

Contact AT&T Customer Service

In the event that none of the above solutions have worked for you, you may want to contact AT&T customer service. A customer service representative can only check your account to see if the problem is there.

Alternately, you can use Internet Explorer’s built-in community features to resolve AT&T account issues. For uncommon or new problems, use the AT&T community forum to share your concerns with other users and look for answers.
