Wi-Fi calling is a carrier-provided feature which allows you to make phone calls and send text messages where U-M Net Wi-Fi is available but cellular coverage is inadequate. You can call and text (SMS/MMS) as you do on the cellular network.
You need to make minor configuration adjustments on your cellular phone to activate Wi-Fi calling. Once enabled, cellular phones automatically use Wi-Fi calling when needed.

Wi-Fi Calling and Emergency Services
During setup, you’ll be prompted to include an address for 911 emergency call routing. The address for 911 emergency call routing helps first responders locate you at the address where you are most likely to use Wi-Fi calling. When you place a 911 call, it uses the cellular network when possible. If no cellular network is available, device location data from nearby Wi-Fi networks can be used to help locate you. If that data is not available, the address you provide during setup will be used.
