Wi-Fi Calling

A common problem that many students and staff face on campus is poor or no cell reception. This can affect your ability to place and receive calls using your mobile device. One possible solution is to use Wi-Fi calling, which allows you to make calls using FGC’s Wi-Fi network instead of your carrier’s cellular network.


  • In order for Wi-Fi calling to work, your device must be connected to a Wi-Fi network with an internet connection. The college provides the FGC_Wireless Wi-Fi network free of charge for all campus visitors.

  • Calls made using Wi-Fi calling will likely disconnect when you move out of range of Wi-Fi, regardless of whether you have cell service or not, as an active call cannot be seamlessly transitioned from Wi-Fi to cellular service.

  • While Wi-Fi calling may allow you to place and receive calls using your device, text messages (SMS) likely will not see any benefit, as that technology typically requires carrier service.
