Wi-Fi Calling

Summary

These steps will demonstrate how to enable and use Wi-Fi Calling on a smartphone to make a voice call.  With Wi-Fi Calling, you can make or receive a phone call if you have a Wi-Fi connection in an area with little or no cellular coverage.

Requirements

• Wi-Fi is turned On
• An active wireless Internet connection - Wi-Fi calling works best when connected to eduroam
• A Wi-Fi-Calling compatible device with appropriate settings enabled - depends on the device manufacturer, OS, and cellular service carrier
  • See suggested troubleshooting steps for guidance below
  • You might need to enter or confirm your address for emergency services.
  • Some devices or cellular carriers may not support Wi-Fi Calling
• In some cases an active cellular network signal is required to turn on the Wi-Fi Calling, (only afterward it is not needed), and you may need to move to a different physical location to complete this process
