If you are having trouble making calls or texts on campus from your phone, calling and texting over WiFi might work for you.  With WiFi calling, you can make or receive a phone call if you have a WiFi connection in an area with poor or no cellular coverage.  Many mobile devices and carriers now support making calls and sending text messages over WiFi when cell service is poor or unavailable.  (Please contact your cell phone carrier, if you have any further questions.)

These steps will demonstrate how to enable Calling and Texting over WiFi:  


  • WiFi is turned On.
  • An active wireless Internet connection - WiFi calling works best when connected to WolfieNet-Secure.
    • An active WolfieNet-Secure network requires an active Stony brook University NetID network account.
  • A WiFi calling compatible device with appropriate settings enabled - depends on device manufacturer, OS, and cellular service carrier.
    • See suggested troubleshooting steps below for guidance.
    • When using WiFi calling, you'll need to enter or confirm your address on Campus for emergency services. 
    • Some devices or cellular carriers may not support calling over wifi. (See Carrier List Below)
  • In some cases an active cellular network signal is required to turn on the WiFi Calling, (only afterward it is not needed), and you may need to move to a different physical location to complete this process.
  • Please note that your call may temporarily drop while walking between access points while on a WiFi Call.
